Description

[0001] HYBRID RECOIL COMPENSATOR

[0002] The invention in question is a hybrid recoil compensator that has a tube frame, fixed to its first end a cam plate, and fixed to the other end a rear plate and a bullet channel.

[0003] The intention of the invention is to add shooting safety in general, the ease of shooting, accuracy, and getting prey by reducing max bang, and recoil when shooting. With the help of the invention one can transfer great recoil arms not suitable for shooting suitable for shooting and remove fear when shooting.

[0004] The scope of usage of the invention is the rifle recoil compensation. One favorable usage is hunting rifles.

[0005] The hybrid recoil compensator according to the invention is equipment that is different from the silencer and muzzle brake for compensating the recoil in its operation and construction. The hybrid recoil compensator is a combination of those. The recoil removal happens in the invention without adding the sound pressure, by cutting the max bang. It is mainly intended for civil hunting to facilitate shooting.

[0006] The hybrid recoil compensator according to the invention does not meet the EU directives set for the hearing protection like the gun silencers in the market nowadays, e.g.

[0007] 9,3x62 ear 149-152 db c-peak, but it only operates in the hearing damage area.

[0008] It is known that the silencer recoil compensation is usually 10-15 % in cases of greater widths.

[0009] The muzzle brake adds the sound pressure 6-10 db when the hearing damage is notable. The bang pressure can double or grow even greater in comparison to the barrel sound (sound without the muzzle brake) and in addition to that the pressure effect is directed in part to the shooter. The increased bang pressure and the pressure effect are problems of the muzzle brake because hearing protection is often lacking when hunting.

[0010] The mass of the silencer removes the recoil efficiently with a light arm like 308 win. This has been tested with Thompson Center encore 308 Win, weight 3.4 kg when the recoil compensation was 300 g with a silencer about 30 %. About this 2 / 3 is caused by the mass and 1 / 3 by silencer. The round was Fiocci 150 with a grain bullet.When the caliber is 9,3x62 (rifle Tikka M690, 4.2 kg) the mass of the bullet, loading, and gun rises in comparison with the former one and when using the same silencer the recoil compensation drops about to 15 % when using firing range round. When shooting with a hunting load the recoil compensation is even less than this, about 12 %. When testing the round Norma Jaktmatch, 225 grain. When increasing the load and the bullet the growth of the mass of the rifle takes power and it cannot be compensated.

[0011] When the caliber rises to 45 the recoil compensation decreases even more and when the bullet flying opening increases the through blow increases. Just where the recoil is greatest the silencer is weakest as the recoil compensator.

[0012] The before mentioned recoil changes are based on measuring that the applicant has made using about 150 mm reflex-silencer. In the measurements that the applicant has made and when comparing the applicants own prototypes with the comparison silencers with the reflex-construction (the inner part comes on the barrel) a few percent increase in the recoil compensation has been acquired but often this increase in operation can also increase also volume and mass. The variation in the silencers' recoil compensation ability has been about max 5 % in spite of the size of the silencer when the mass has been removed from the formula.

[0013] The silencers meaning is as known to increase the pressure release time as long as possible to get the bang reduced. The muzzle brake in turn requires a high flow and a sufficient head cup surface and the change of flow direction that gives the recoil compensation. The release of the pressure must happen into an open space when using the muzzle brake. In a closed space the muzzle brake does not work to compensate the recoil but as a reducer of flow, that is as a part of silencing. The advertising seems to show misleading impressions around the recoil compensation to support the marketing.

[0014] In the marketing of the silencers the recoil compensation has a big role. The adjectives like "meaningful" and "excellent" often define the recoil compensation. It would be possible to make a general measuring instrument and it would be easy also but it hardly would support the sales, maybe vice versa. The recoil compensation of the silencer operation is almost constant, the variation is small. When the mass variable of the silencer is ruled out the differences in recoil compensation of the silencers are very insignificant.Following come results of the practical tests and measurements that the applicant has made:

[0015] Example 1.

[0016] A silencer in the market, weight 366 g, gave exactly the same recoil compensation as the applicant's own 290 g prototype silencer. So the difference in weight was 76 g. In the own silencer of the applicant that contained hybrid recoil compensator disk a higher recoil compensation was reaches with the inner construction in relation to the known silencer to compare. The test gun was 3.4 kg TC encore 308 Winchester, 150 grain round. The applicants own prototype was a 60 mm gun length increasing (front overhang) 90 mm long silencer. The comparison silencer was about 100 mm gun length increasing front silencer with the total length of 120 mm. In this weight class 100 g extra mass causes 7 % increase in recoil compensation with 308 win caliber. The calculation advantage is in this case about 5 % for the advantage of the applicant's own construction. So here is only silencer construction without muzzle brake in a considerable smaller volume. The reliability of the measurements is supported by the big number of the samplings and the measuring of quite similar new prototypes. The phenomena has been seen in many measurements. Year 2024 there were over 100 measurement situations (the applicants own silencer vs comparison silencer).

[0017] Example 2.

[0018] In the caliber 9,3x62 Tikka M690 gun 260 g silencer the applicant received recoil compensation of 15.5 %. The meaning of the mass factor of the silencer for the recoil compensation is reduced considerably when moving to heavier big caliber guns. For example when the weight of the gun is 4.2 kg with a sliding sleeve and using a factory loaded firing range round that has a 15 g bullet and a hunting bullet of 18.6 g the recoil compensation of 12.7 % was achieved in the applicant's measurements.

[0019] With a 300 g punt, that is a dead mass addition, the applicant received a recoil compensation of 11.6 %. We can deduce from this that the silencer itself is very weak in the recoil compensation.

[0020] Example 3.With the width 45, a caliber 444 gun the recoil compensation that was caused by the silencer was 8.9 %. It was a self loaded max loading into a shell and the bullet was 15 g. Same model and type as example 2 but larger hole.

[0021] Where the recoil compensation is most needed it is hardly achieved with a silencer.

[0022] Example 4.

[0023] In caliber 308 Win three reflex-silencers were measured. The rifle was TC encore folding barrel rifle. The diameter of every silencer was 50 mm and the front overhang 68-67 mm. The length of two comparison silencers was about 150 mm. Model 68 / 98 with hybrid recoil compensator according to the invention was about 50 mm shorter of the reflex-tube that comes upon the barrel. As to the volume the two comparison silencers had about 1 / 3 handicap. 5 shots were measured with every silencer. The impact energy to the shoulder was measured in a recoil stand, results:

[0024] Comparison silencer 1, length 150 mm, acquired as an average of 5 shots 137.2 cm long movement and a relative 24 % relative recoil compensation.

[0025] Comparison silencer 2, length 150 mm, acquired the average of 5 shots of 130.5 mm movement and 28 % relative recoil compensation.

[0026] A silencer with a disk according to the invention, length 97 / 67, acquired a 5 shot average a 125.6 mm long movement and 30 % relative recoil compensation.

[0027] The weights of all the silencers were 390 g +-3 g. This way, the weight was sealed out of the test. In spite of that the volume was one third smaller as the silencers had the hybrid recoil compensator disk according to the invention it was the most efficient.

[0028] Measured by the ear, the before mentioned applicant's device 97 / 67 received a 5 shot average of c-Peak scale value of 136.2 db. The comparison silencer 1 got the value of 139.4 and the comparison silencer 2 the value of 138.0 db.

[0029] As a resume we can say that a good recoil compensator is also a good silencer. In this measurement the recoil stand operated also as a mechanical bang gauge. When the silencer reverses the flow energy the sled does not back and the sound is low. When the muzzle brake is added the situation changes and bang is changed to recoil compensation.The silencer is nevertheless mainly silencer and not a recoil compensator. There is no special capability that would make the compensator a muzzle brake like something. Only by adding bang and changing flow direction into a free discharge space the recoil compensation can be made good. The measurements are based on five different commercial comparison silencers (4x reflex silencers and 1 front silencer) and the applicant's own equipment.

[0030] The weather can affect the silencing even 6 db and therefore the comparison is important. For instance the relative air humidity can vary 30-90 %. By performing comparison measurements in different weather conditions the applicant has found out the capabilities of his prototypes in relation with the comparison in different conditions.

[0031] When the diameter of the bullet channel of the silencer grows the silencing gets weaker, flow through increases and the recoil compensation gets weaker.

[0032] In one USA recoil compensation publication some 20 muzzle brakes were measured. The two best muzzle brake results the bullet channel diameter was greater than others. So the pressure peak is worth to take into account in every chamber that the width allows. Eyebrow damages still occur in spite of the use of the silencer. A hunting day can end in a health center visit. This is possible from the caliber 9.3 on. Also the magnum widths 338 and 375 have high recoil. When seen from the stand even 308 and 30-06 widths can be unpleasant for some shooters. When shooting lying down the risks are even bigger.

[0033] The frame tube 45 mm is used generally in caliber 7.62 mm gun silencers. It works well in this width. As the caliber grows it is no more sufficient. Continuing the length with elements adds mass to an end of lever arm and the possible line error risk grows because the clearances between male and female threads vary from gun to gun. The long front silencers do not belong to the dangerous risk hunting. Growing tube diameter is another alternative but producing two models instead of one model is not cost effective and thus understandable.

[0034] The silencers are generally produced using a tight clearance. It is important to balance the bullet and the inner constructions have been made to stand contact. This is the way to get maximal silencing. The smallest diameter that the applicant has measured in thebullet channel in the caliber 7.62 mm silencer has been 8.3 mm. If the silencer disk clearance was 1 mm greater it would reduce the silencing by 1.5-2 db.

[0035] One known way to try to achieve silencing bang and compensate recoil is to join to the silencer a separate muzzle brake. With the search words "Suppressor-ready muzzle brakes" one can find this kinds of solutions.

[0036] The recoil compensation ability of an ordinary silencer is insufficient in big caliber guns and when the fear of recoil weakens the shooting accuracy suffers. Strong recoil can also cause physical damage for the shooter. Forceful recoil can also cause the risk of the dangerous prey to attack the hunter for instance because the second shot becomes more difficult to shoot quickly.

[0037] The known front silencers are over long and this causes the inconvenience that their thread connection in the gun loosens when they get warmer and the silencer trembles in relation to the barrel line. The longer the silencer the more it stores warmth in the thread connection. The construction kind of gets a bending hinge by the loosened thread connection and long silencer caused bending momentum. This inconvenience is the greatest when the only support of the silencer is the thread. The inconvenience can be reduced by using guide organs but cannot be eliminated altogether. Even a small hanging of the silencer causes damages and especially in hunting of the dangerous prey the front overhang (distance from the barrel end to the silencer end) is a safety risk. With a long front silencer all the problems are accentuated.

[0038] The known silencers are complicated cell constructions equipped with different fiber fillings and when they form the muzzle brake, "suppressor ready muzzle brakes", an equipment like the solution so its weight and length increase even more and bring along a number of problems that have been mentioned earlier where the leverages and the difficulty of shooting another shot are not the smallest.

[0039] It is known that the recoil compensating ability of the silencers in the market is bad especially in big caliber guns.

[0040] That the known muzzle brakes double the sound pressure (6-10 db) and cause pressure bang, this is one known technology clear drawback.The hybrid recoil compensator according to the invention can be made for instance with frame tube diameters 40-60 mm and with a small front overhang up to the clearance 45. When using the hybrid recoil compensator according to the invention the basis for the accuracy shooting can be seen the following clearances:

[0041] Fast magnum guns require clearance 1.5 mm all around, which is +3 mm upon the caliber. This has been tested with tens of magnum guns in practice, e.g. rounds 300 Winchester magnum / short magnum, 338 Winchester magnum / Lapua magnum, 375 H&H, 338 Lapua magnum, 416 rigby etc.

[0042] Instead, a slow bullet is more stabile with rounds like 458 Winchester magnum 45 / 70 which operate with a smaller clearance.

[0043] Also too light and short bullet in wrong angle of rifling needs more clearance, the trouble occurs often in caliber 30-06 that is often used to shoot light bullets.

[0044] The clearance brings accuracy that is always primary. The added flow-through increases the recoil compensation. The sound is changed to the recoil compensation without negotiating about the accuracy.

[0045] The invention is realized favorably using clearance 1.4-3 mm + caliber depending on the width. This means to assure the free flight of the bullet without contact. As the flow-through increases another capability that is the recoil compensation gets better. In the silencer the effect is the other way round.

[0046] The invention can be realized using short front overhang and a fair hole. This brings security especially when hunting dangerous prey.

[0047] A clearance of the type of 1 mm + caliber is anyway typical in the known silencers. The contact is then almost constant depending on the construction and the silencer operates in some parts as rifling free inside barrel. The added silencing is important when the accuracy is not measured. The space that the bullet requires is highest about 30-40 mm from the barrel out end.A 150 grain bullet in caliber 300 Win mag it is possible to measure over 60 % recoil compensation using the hybrid recoil compensator according to the invention. Heavy pressure and a light bullet cause this result. If the flow-through increases in the silencer part of the hybrid recoil compensator the muzzle brake reacts to the added flow-through compensating more recoil. The affect is so opposite to the silencer. The sound is exchanged to the recoil compensation. The greater problem about recoil to the silencer the greater help is achieved from the hybrid recoil compensator.

[0048] The recoil compensation ability of the hybrid recoil compensator according to the invention can be about 2-4 times as good in comparison to a silencer. In this claim the weight factor has been removed. The measured capability values of the present hybrid recoil compensator come mostly in the area 45-60 %. For example about the air pressure in caliber 9.3x62 is about 149-152 db that corresponds in this situation 16-20 caliber shotgun measured from the shooter's ear.

[0049] The increased brake energy is obtained in the invention by adding the air pressure. With the plain muzzle brake can give over 70 % recoil compensation (barrel 40 cm - 330-06). By the applicant measured muzzle brake recoil compensation has been 15-72 %. The best result came from the applicant's own product. The weakest muzzle brakes are thin thickly perforated aluminum brakes because of small mass and cross-sectional area in the brake perforation.

[0050] The traditional silencers are produced based on EU standard set values. 137 db, c-scale limit value for hearing protection, directive 2003 / 110 / ec 137db(C). The hearing damage limit is thought to be 140 db. Typically 137 db is achieved with about 120 mm long front silencer in caliber 308 Win. The hybrid recoil compensator according to the invention is always produced shorter. The invention does not meet these limit values. Just this lower silencing gives the increased recoil compensation that makes a magnum gun possible to shoot.

[0051] The traditional silencer halves the air pressure four times from 24 db or five times from 30 db. The hybrid recoil compensator according to the invention operates in the barrel bang or halves the air pressure once or twice being usually between 0-12 db. 12 db means two meters as a distance. The muzzle brake easily doubles the bang. At its maxi-mum bang line from end to end the bang pressure is 6 times halving from top downwards.

[0052] The hybrid recoil compensator according to the invention is a compromise between a silencer and a muzzle brake. The cam plate cross-section area is large in this one gate hybrid recoil compensator in comparison with the traditional muzzle brake. With a 2 gate brake part it was not gained in spite of the addition area additional capacity.

[0053] The first gate of the traditional muzzle brake is too small by area. The pressure max looses energy through the first gate, over flow happens and the gates 2 and 3 function insufficiently. A small diameter does not make possible additional brake efficiency which in turn can be found in hybrid recoil compensator. Enlarging the hole in the muzzle brake can sometimes increase the brake efficiency. Gates 2 and 3 work more and cause no over flow in gate 1.

[0054] The equipment according to the invention is competitive and suitable firstly to guns to hunt big prey. Also a hunter of small size can get from the product considerable help when shooting even in caliber 308 Winchester.

[0055] The development curve of the invention is affected essentially the factor that the air pressure and recoil have both been measured at the same time taking into account both factors. It is essential to find the best compromise.

[0056] In bang measurement the military standard has not been used. The bang measurement from the side of the shooter is suitable for the military use: hearing protection in the trenches. The hybrid recoil compensator removes pressure just for the side sector.

[0057] Adding a muzzle brake to a traditional silencer does not give a good result. A reduced flow does not give the hoped recoil compensation.

[0058] Easier handling of the gun increases also the ease of the cover-up shot. This adds safety especially when hunting dangerous prey. A long front silencer represents the opposite. When using the hybrid recoil compensator according to the invention a rapid second shot is easy. Gun sight view remains almost the same. The pressure effect is directed through the side openings mainly to side sectors not towards the shooter or the dog.The pressure effect is directed towards the side sector, not front or back. This makes the situation of the dog and shooter easier.

[0059] The disk of the hybrid recoil compensator according to the invention which disk's meaning will be introduced in more detail later is essential for the recoil compensation and silencing. The muzzle brake has the task to amend the recoil compensation especially with the heavy-duty guns. To add the muzzle brake to the equipment according to the invention changes the situation so that silencing is exchanged to the recoil compensation. The invention has a short front overhang, for instance 58 mm and it enables the equipment's short even considerably under 100 mm total length and thus the reflex tube thread part is near the balance point of the hybrid recoil compensator. Because of this the leverages affecting it are small. This is a meaningful advantage in relation to the known technology the combinations of which are even over 300 mm long.

[0060] The equipment according to the invention and its usage are not subject to license because the sound they silence can be over the license limit. The freedom from the license means many kinds of advantage: freedom from control, from book keeping and the usage of the gun rooms for this reason.

[0061] The intention of this invention is to achieve such a hybrid recoil compensator that eliminates drawbacks of the known technology. It is characteristic for the invention solution what has been presented in the characterizing part of the claim 1.

[0062] The invention is described in more detail in the enclosed drawings where

[0063] figure 1 shows the invention in 3D,

[0064] figure 2 shows the invention directly from the side,

[0065] figure 3 shows cut A-A in the previous drawing,

[0066] figure 3a shows the point C of the previous drawing zoomed,

[0067] figure 4 shows a part of the invention seen from the side,

[0068] figure 5 shows cut B-B from the previous drawing,figure 6 shows a clear chart about the known silencers and invention recoil compensation abilities.

[0069] Next the construction and operation of the hybrid recoil compensator according to the invention are explained referring to the mentioned figures.

[0070] In the applications of the figures 1, 2, and 3 presented invention solution is the hybrid recoil compensator 100 that consists of a tube frame 1, a cam disk 2 fixed to its first end, a rear disk 3 fixed to its other end 1.2, inside the hybrid recoil compensator directed, fixed to be an extension of the rear disk reflex tube 4 and fixed to the gun barrel, two mid disks 5 and a bullet channel 6. In figure 4 it has been presented the mid disk 5 separately and in the figure 5 its cut B-B. The tube frame 1, the cam disk 2, and the rear disk 3 form with the inlet and outlet openings of the bullet channel a gas tight construction when the invention does not have side burst openings 7.

[0071] In each mid disk 5 there is an opening 5.1 that belongs to the bullet channel and is same centered with it, and a wing 5.2 that has been fixed to the tube frame from its outer circle entirely and a flow guide 8a that has been formed to its release side so that it has been adopted to turn the gun powder flow into the reverse direction. In this favorable invention example the tube frame is a cylinder.

[0072] To the cam disk 2 there has been formed with even distribution symmetrically four side burst openings 7 and to the cam disk 2 and to the reflex tube 4 there has been formed the flow guides 8b / 8c.

[0073] The hybrid recoil compensator 100 according to the invention is by its construction compact; all its versions are essentially shorter than the conventional silencers and hybrid solutions made of then by adding a muzzle brake in the market. The flow guide 8b of the cam disk 2 is in itself a known solution but its invention like shape that will be presented later, adding the mid disk 5 to the construction and the flow guide 8a of the invention give together an essential extra for the recoil compensation.

[0074] The bullet channel 6 is always as known larger by diameter than the bullet and the difference between these diameters divided by two is the clearance 6.1. It can always be realized in the inventions as desired and all around the same.The invention functions as follows: When the bullet arrives to the opening 5.1 of the first mid disk 5 (a part of the bullet channel) a great deal of the gun powder gases guided by the mid disk wing 5.2 favorable curvy profile into the first chamber 9 and rotates to the rear disk 3 and to the flow controller 8c of the reflex tube 4. At that moment, only a little part of the gases flow through the clearance 6.1 into another chamber 10. As the bullet arrives to the second mid disk opening 5.1 the mid disk changes the direction of the gases following the bullet like previously and they turn in the second chamber 10 second mid disk flow guide 8a that brakes, changes and mixes further their flow. Next, the bullet following gases flow direction change happens in good order the next mid disk (if there are more of them than two), etc, and lastly the gun power gases bump at the cam disk 2 flow guide 8b curvy surface from where the gas flow hits the side burst openings 7. The mentioned surface turns the direction of the gases in the same way as the mid disk wing 5.2 and the side burst openings burst the gas efficiently through the tube frame 1 openings through its outer surface to the sides symmetrically. Because of the symmetry, the out bursting gas does not unbalance the gun.

[0075] The forced collisions of the gun powder gas, direction changers, and burst out in out to sides compensate efficiently recoil in the invention even with short construction length. Because of the invention, two things happen after the shot: the hybrid recoil compensator 100 according to the invention reduces the recoil caused by the before described braking effect and then the bang increases and at the same time the inner parts of the equipment silence the sound. The invention is thus not a silencer even though certain parts of it silence the bang. With certain calibration the invention can be set to reduce the bang in addition to compensate the recoil but as said earlier its intention is not to reduce sound under the national or international hearing damage limits.

[0076] The recoil compensator 100 according to the invention can also be realized without the reflex tube 4 in which case it is fixed to the barrel outer thread by the inner thread of the rear disk 3 opening. In these so called front silencers the flow guide 8c is connected directly to the rear disk 3. In this solution it is possible to form in the rear disk 3 a flow guide using the same principle as the cam disk but directed reversely.In the hybrid recoil compensator 100 according to the invention with the reflex tube 4 there is a pit 4.1 where the gun barrel end is put and the hybrid recoil compensator is fixed to the gun barrel end outer thread using the inner thread of the reflex tube hole 4.2.

[0077] The invention at hand can operate in the hearing damage area whereas the silencers are set to operate to silence the sound under some country or area, e.g. EU, ordered norms that are for instance at level 137 db - 140 db.

[0078] The hybrid recoil compensator 100 according to the invention can have one or more mid disks 5. In figure 4 of the above example mid disk has been shown from side and in figure 5 its cut B-B. The solid wing 5.2 of the mid disk has been formed concave so that it forces the gun powder gases turn in the chambers 9, 10 into a reverse movement and to dissolve the flow together with the other surfaces in the chamber. The flow guide 8a in the mid disk takes part in this concerning the gun powder gases turning back by the in order next mid disk.

[0079] The flow guides 8a-8c are in the above example by shape like cut circle cone rings through which the bullet goes and where the cone outmost string is a line or concave like a horn and the bullet goes through them and where the cone profile outmost string is a line or concave like a horn and are thus able to change the direction of the flow direction of the gases. As can be seen from the drawings the flow guides have been adapted in the example at hand also face to face so that all their profiles are not to the same direction. With straight and concave outmost string shape the same performance has been obtained in the measurements.

[0080] Placing two flow guides 8a-8c face to face added performance is obtained as flow braking part is joined to the recoil compensated in the out way chamber (the last chamber 11). Flow guides can thus be adapted to the cam disk 2 (8b), reflex tube 4 (8c), and mid disk 5 (8a) or in some cases only in part of this. If the construction does not include reflex tube 4 the flow guide 8c can be integrated to the rear disk 3.

[0081] Figure 3 shows the flow guide 8b in the cam disk 2 between the side burst openings 7 and the bullet channel 6 that comes from the inside surface of the cam disk to the last cham-ber 8b of the hybrid recoil compensator. This causes the max discharge of the pressure into the side outburst openings 4 and adds recoil compensation instead of releasing more pressure from the out way of the bullet channel 6.

[0082] It is favorable to locate the flow guide 8b to reach over the side burst openings 7 to the last chamber 11 to turn the gunpowder flow into the mentioned openings and in order to reduce the gas flow through the bullet channel. The figure 3 shows for clarity the distance of the back edge 7.1 of the outburst openings 7 from the out circle inside circle inside surface by marking m and the distance of the head 8b.1 of the flow guide 8b from the cam disk out circle inside surface by marking n. Thus n>m applies in the invention. To the sides of the flow guide 8b in the direction forward sloping bullet path the before defined shape has a favorable effect to the recoil compensation in all the applications of the invention.

[0083] The hybrid recoil compensator 100 according to the invention can have a desired amount of the side burst openings 7. To achieve symmetry there should be at least two of them and four is one favorable amount because then the pressure can be divided around the equipment. The size of the side burst openings 7 can be adapted optimal case by case. The side burst openings 7 have been adapted to in the above example behind the cam disk 2 but if desired they can also be located in the cam disk.

[0084] The invention can also be realized without side burst opening 7 when the gun powder gases turn efficiently backwards from the cam disk flow guide 8b. Especially when the loadings remain under 2.5 grams it is favorable to realize the invention without the side burst openings 7.

[0085] After a Sako-thread fix it is possible to install on the barrel outer surface a heat resistant o-ring. The reflex tube 5 is as standard 3 mm greater than the barrel diameter.

[0086] As a safety measure against the loosening of the hybrid recoil compensator 100 an o-ring can be used that supports it like a spigot guide. In this case, a groove 3.1 has been formed to the rear disk 3 where the heat resistant o-ring can be adapted to support the hybrid recoil compensator to the barrel of the gun as the construction gets warmer. The figures 3 and 3a show one this kind solution. The groove 3.1 has been formed to the corner ofthe pit 4.1 and the rear disk 3 front surface 3.2 and the o-ring 12 has been adapted there so that its bullet channel 6 center line cl side part reaches deeper than the pit 4.1 surface inside the pit (see the measure p). This secures that the o-ring tightens the joint.

[0087] The mid disk 5 according to the invention can also be used in a traditional silencer in which case it forms equipment according to the invention. The space efficiency capabilities have been developed exactly during the development work of the silencer.

[0088] The hybrid recoil compensator 100 has a part that slows the flow, a silencer part, and a flow direction change recoil compensating part. These can be benefited separately in the production of the silencer or the muzzle brake. Both parts are separately very efficient. It is favorable to produce the hybrid recoil compensator 100 according to the invention from steel. The tube frame can be made for instance from a standard (round) suitable size tube and the other parts for instance of a plate by pressing. Fixing the parts to each other can be made for instance by welding. The material can also be some other than steel and all the methods to produce the parts and fix them realize the invention. It is essential for the invention that producing it is considerably easier and cheaper than comparable other known products like for example combinations of a silencer and a muzzle brake. The equipment according to the invention can have the length I under 100 mm but this does not limit its max length.

[0089] It should be noticed that even though this explanation sticks to one type for the invention favorable realizing example this does not want to limit the usage of the invention to concern only this type of example but instead many variations are possible in the scope defined by the claims' invention idea.
