The invention relates to hand firearm and is aimed at improving the ergonomics of firearm with a bullpup layout.

The specified technical result is achieved by the fact that the bolt of the firearm has an extension of the bolt handle, which makes it possible to position the bolt handle near the trigger, thereby facilitating the process of reloading the firearm.

A shotgun ammunition conversion system has a detachable magazine well having a sleeve defining a rectangular passage adapted to removably receive an ammunition magazine, a boss extending forward of the sleeve and at a level above at least a portion of the sleeve, the boss being adapted to be received in the rear aperture of the magazine tube, and a tang extending rearward of the sleeve and defining a tang aperture operable to receive a fastener associated with a shotgun frame to secure the magazine well to the shotgun with the sleeve proximate and aligned with the loading port when the boss is received in the rear aperture of the magazine tube. The boss may have a lower cylindrical surface portion operable to contact a lower portion of the magazine tube adjacent to the rear aperture. The boss may be a cylindrical body.

A cap that is intended to obturate a duct for ejecting cartridges of a turret. This cap includes a circular base that is intended to allow it to be fastened to the duct, and a body shell having a spherical dome profile including a concave face and a convex face, the body shell being divided into at least four sectors by radial slits that are regularly distributed angularly, the sectors being contiguous pairwise. Another subject of the invention is a turret including a duct for ejecting cartridges equipped with such a cap.

A device for deflecting links intended to equip a turret equipped with a weapon with a dual-feed for ammunition belts formed by links. This device is characterized in that it includes a deflector flap that is intended to be disposed between two orifices for ejecting links out of the turret, which flap is intended to be connected to the weapon by a fixing means including a ball joint connection disposed towards the front of the weapon, and a horizontal slide connection disposed towards the rear of the weapon. Also, a turret equipped with such a deflector.

Improvements to firearms that load cartridges from a magazine and/or a clip are disclosed. Specifically, improvements to slide assemblies and bolt assemblies to depress a cartridge in a magazine and/or a clip are provided. Such improvements include a sloped bottom-facing surface of the slide assembly and/or bolt assembly. The sloped bottom-facing surface is sloped along the length of the portion that contacts a cartridge in the magazine and/or clip when the slide assembly and/or bolt assembly reciprocates.
