A magazine spring includes intermediate coils each having a first end portion, a second end portion, and a waist portion between the first end portion and the second end portion. The waist portion has a width that is less than a width of at least one of the first end portion and the second end portion. A magazine tube is also disclosed. In one example, the magazine tube is made of sheet metal and includes grip indentations formed along forward corners of the magazine tube. The magazine tube may also define locating ribs for blank cartridges. A magazine spring having the narrow waist portion can be included in the magazine assembly so that the spring clears the locating ribs.

The application discloses a small celestial body penetration anchoring test platform and a test method thereof. The test platform comprises a main structure, a simulated asteroid container, a launching unit, a speed meter, a camera, a force steel wire, a tension meter, a rocker arm, and a rocker arm support. The launching unit comprises a mounting plate, a base, a launching cylinder, a piston, a cartridge, a ejector pin, a recovery spring, an electromagnet, an anchor body, a buffer pad, a flange, an ejector pin support, and a pose adjustment groove. The cartridge is internally provided with air holes, so that the penetration depth, the penetration trajectory, and the anchoring force of the anchor body in different speeds, different penetration angles, and layered asteroid soil can be tested. The anchor body penetration power is provided by a blank cartridge, and the blank cartridge is triggered by the electromagnet hitting the ejector pin. The application has the characteristics of high test efficiency, full test coverage elements, low cost, safe and simple operation, and the like.

The invention provides a multi-hole automatic feeding CNC integrated machining device and method, and relates to the technical field of CNC machining. The device comprises a clamp, a jig, a stock bin, a finished product taking clamping jaw and a tray taking clamping jaw, the jig is provided with a plurality of sets of charging holes and corresponding clamping assemblies which are rotationally symmetrical by 180 degrees, and the stock bin comprises a blank magazine and a finished product tray. According to the method, automatic feeding is conducted through the blank magazine, blanks are fixed through the clamping assembly, after CNC machining, finished products are transferred to the trays through the finished product taking clamping jaw, after full loading, the tray taking clamping jaw transfers and supplements the empty trays, and meanwhile the two sets of material cavities conduct machining and feeding alternately. Automatic continuous machining of the 3C type parts is achieved, the machining precision is guaranteed while the process is simplified, and the method is suitable for mass production scenes.

An ammunition cartridge casing has a casing base with a proximal end surface, a casing body defining an inside volume, and a distal end portion. The casing base defines a primer pocket in communication with the inside volume of the casing body, where the primer pocket is sized and configured such that when a primer is installed in the primer pocket, a proximal face of the primer is recessed into the base at least 0.010″ with respect to the end surface. Blank ammunition made with the cartridge casing is configured for use with a rifle having a bolt with a boss on the breech face that corresponds to the recessed primer.

A training and testing blank firing adaptor cartridge chamber for certain large caliber firearms such as grenade machineguns is provided. The blank firing adaptor cartridge chamber utilizes smaller caliber, low-cost blanks as the powering source to achieve realistic operating mechanism functioning.

The present application relates to ammunition technical field, especially a kind of full shape blank cartridge for completing disintegration after projectile ejection by launching energy, it is composed of launching charge and projectile, the projectile includes bullet body, wind cap, pressure limiting sheet and counterweight filling;The bullet body is the structure of the cylinder with one end sealed and the other end open, it is equipped with fire hole in sealed end, the fire hole is covered by pressure limiting sheet on the outside of sealed end, and the sealed end is partially assembled in launching charge, the open end of bullet body is buckled with wind cap;The counterweight filling is filled in the inner cavity of bullet body.The present application relies on the structural design of projectile to ensure that it has similar interior ballistic performance with standard product during shooting, and the sensory experience is basically consistent with live ammunition shooting, it can be used for training soldiers to master the basic shooting action of grenade launcher, also can be used for live exercise, fill the blank of grenade on blank cartridge;The projectile does not contain any dangerous sensitive material such as explosive, no explosion danger.

The present invention particularly presents a device for converting a weapon capable of firing only blank ammunition (A) into a less-lethal projectile launcher dedicated to temporary neutralization, comprising a frame (10) of longitudinal shape along a central axis (X), and fixed on the picatinny rail of the blank weapon by bolts (11) and which serves as a support for the barrel (12) and the magazine (15) capable of holding an equivalent number of projectiles to the magazine of the blank weapon (A).
