Apparatuses and methods are provided for an optimized direct gas operated firearm. The firearm includes an upper receiver coupled with a lower receiver by a tensioning screw that reduces wobble between the upper and lower receivers. A barrel extension is configured to eliminate misalignment during installation into the upper receiver. A bolt carrier includes a reinforced bolt assembly and a forward-biased dwell weight. The bolt assembly includes an extractor and an extractor pin that simplify disassembly of the firearm. A handguard includes locks that attach to a barrel nut area of the firearm. The locks clamp onto the barrel nut area to align the handguard with the upper receiver. An ambidextrous bolt catch release assembly is operable from either side of the lower receiver. A bolt catch release paddle is disposed at the front of a trigger guard to provide easy access from either side of the lower receiver.

The application discloses a kind of remote control training projectile, which includes projectile tail assembly, projectile belt push-pull mechanism, axial limiting block, operation control module, trapezoidal screw rod, projectile shell rear section, projectile shell front section, display controller, fuse, remote controller and the like.The remote control training projectile uses remote control command mode to control operation control module to output rotary motion and torque according to set program, and the trapezoidal screw rod drives the projectile belt push-pull mechanism to realize the radial expansion and contraction of nylon projectile belt.The radial expansion and contraction of nylon projectile belt can reliably compress the training projectile in the barrel of the gun or release the compression to automatically eject the projectile.The application realizes "one-key ejection" through remote control command mode, completely eliminates the "ineffective labor" of manual ejection operation during the training of soldiers, reduces the physical consumption of participating soldiers, greatly improves the training efficiency, and realizes the complete continuity of the training process.Meanwhile, the remote control training projectile also has the function of manual ejection under the condition of electrical fault, which can effectively avoid the interruption of the training process.

Provided is a downward ejecting bullpup firearm with a detachable magazine having a downward facing ejection port rearward of a magazine well. A top inspection window is positioned substantially in vertical alignment with the magazine well. A charging handle body has a rear portion and a forward portion and is movable between forward and rearward positions. The rearward portion blocks the inspection window when the charging handle body is in the forward position and the forward portion has a through-opening that substantially aligns with the inspection window when the charging handle body is in the rearward position.

The invention relates to a grenade launcher for firing bomb-type cased ammunition, known in the art as a launcher. After firing, the empty ammunition casing is removed by itself. Another feature is that the trigger mechanism has been simplified to facilitate disassembly, assembly, maintenance and repair processes.

A rifle having a straight pull bolt assembly with a bolt handle that extends outward and downward from a bolt operation mechanism. The bolt handle rotatable a limited rotational range forward and rearwardly about a horizontal axis for operating the mechanism. The handle can be reconfigured to position its rotational range about the horizontal axis and can be attached to the mechanism at either left or right sides to provide for ambidextrous operation. Bolt heads, lower frame members with magazine wells, and barrel assemblies can be readily swapped to change ammunition. The bolt assembly can be unlocked by firing or by a thumb push button release at the backside of the mechanism. A bolt removal release mechanism is forward of the thumb pushbutton and an ejector includes a spring bias and cam follower surface to reliably eject casings.

Disclosed is an extractor for an autoloading firearm, the extractor having an extractor body extending a proximal end portion to a distal end portion. A knuckle is between the proximal end portion and the distal end portion and defines a pin opening extending crosswise through the extractor, where the pin opening has an elongated shape. During rearward movement of the bolt after firing, the elongated opening enables the extractor to shift downward and / or forward so that part of the extractor contacts the bolt, thereby preventing the extractor from pivoting about the extractor pin.

The utility model discloses a portable ejector of new type for three-seven antiaircraft gun, including fixed calipers, force bar, V type spring piece, fixed screw, the inside of two clamping claws of fixed calipers is equipped with the threaded hole, the opening of V type spring piece is downward, and two ends are equipped in the threaded hole of corresponding clamping claw through fixed screw, force bar adopts fixed A type force bar or two movable force bars, fixed A type force bar includes two force bars and the reinforcing rod fixed between two force bars, and the front end interval of two force bars gradually reduces, and the front end of fixed A type force bar and two movable force bars is hollow pipe, when the antiaircraft gun is ejected, the clamping claw of fixed calipers is located in the barrel extraction cylinder notch part, and V type spring piece is in compression state, and the clamping jaw holds the ammunition cylinder bottom edge part, and the two hollow pipes of fixed A type force bar front end or the hollow pipe of movable force bar front end inserts the two foot positions under corresponding clamping jaw of fixed calipers, the utility model discloses a portable ejector of new type for three-seven antiaircraft gun, uses safety, and simple operation.
