A lever gun has a receiver bearing the whole structure and all other components, a mechanism performing the cocking and locking functions, a trigger mechanism performing the firing function, a barrel through which the fired ammunition is guided towards the target, a magazine storing the ammunition and a lever driving and thus cocking/setting said mechanism. A divider component is positioned at the rear side of said trigger mechanism that does not face the barrel, and at which the lever is centred in order to perform rotating motion, and at least two lever arms perform transmission of motion between the lever and the mechanism, and connected to each other via movable hinges.

A bolt carrier group assembly for a firearm includes at least one metallic bolt carrier group component with an outer metallic surface and at least one insert with an outer surface. The outer surface is at least flush with the outer metallic surface, and the at least one insert has a lower coefficient of friction compared to the at least one metallic bolt carrier group component.

The present invention relates to the field of military technology, and more particularly to an automatic firearm. Said firearm consists of a receiver, a barrel, a bolt carrier and a bolt, a bumper spring on the bolt carrier, a recoil spring between the bolt carrier and the rear wall of the receiver, a trigger mechanism, an ammunition feed mechanism, sighting equipment, a device for locking the bumper spring in a compressed state caused by the bolt carrier striking the front wall of the receiver or the barrel or the bolt via the bumper spring, and a mechanism for synchronizing the release of the bumper spring with the firing of a shot. Additionally, the firearm can be provided with an additional bumper spring between the bolt carrier and the rear wall of the receiver, and a lever for compressing and subsequently releasing said additional bumper spring in case the manual reloading in order to impart additional kinetic energy to the bolt carrier for the forward movement thereof, wherein said lever can be combined with a recharging handle. Additionally, the firearm can be provided with an additional device for locking the bumper spring in a compressed state caused by the bolt carrier striking the rear wall of the receiver via the bumper spring, and a lever for compressing and subsequently locking the bumper spring during the rearward movement of the bolt carrier in the case of manual reloading, wherein said lever can be combined with a recharging handle. The technical result provided by the above combination of features is the creation of a firearm having an inertial automatic loading system that functions reliably and consistently due to the increased reloading system working speeds and increased recovery of recoil energy.

The present disclosure provides ammunition magazines and hold-open bolt carriers for using low-cost (e.g., 22LR) ammunition in a standard AR-15 or M16 upper receiver.

In the fixed frame it has a base, in which a barrel with the axis below the level of the upper edge of the shooter's hand, a trigger, a buffer and a long ejector are attached. A pistol grip with a cartridge magazine is obliquely slid into the frame and attached. A semi-embedded moving slide, containing especially a closed launch pad, a firing pin, an obliquely placed extractor and a rob of the trigger mechanism, is inserted into the frame from above. The slide is covered from above by upper body attached to the barrel and at two points to the frame, which carries sights at the top and has elements of the hammer system placed on the lower side.

A bolt catch device is disclosed. The bolt catch includes a movable surface configured to be positioned within a weapon so as to conditionally engage a bolt so as to prevent the bolt from rechambering a next round from a magazine, a tip configured to, in response to a received force, cause the movable surface to move so as to release the bolt, and a spring engagement feature configured to be positioned within the weapon so as to receive a spring within the weapon, wherein the spring within the weapon is configured to bias the movable surface toward a position which prevents the bolt from rechambering a next round.
