    Abstract: The present invention discloses an air gun. The air gun having a recoil gas unit and a bolt carrier unit. The recoil gas unit comprises a recoil guide tube configured to supply compressed air and a recoil assembly spring for movement of the recoil tube carrier. The bolt carrier unit is coupled to the recoil gas unit and comprises a piston. The bolt carrier unit also comprises a valve chamber for performing a firing stroke of the air gun. The bolt carrier unit comprises a piston chamber. The piston chamber is configured to facilitate movement of the piston and to receive the compressed air, for performing a recoiling stroke of the air gun. The recoil gas unit facilitates the firing stroke and the recoiling stroke of the air gun.

    Abstract: There is provided a bolt action receiver assembly for a semiautomatic lower receiver which may be used to convert a semiautomatic rifle to a bolt-action rifle by replacement of the upper receiver assembly, while retaining the remainder componentry of the semiautomatic rifle. The upper receiver has a magazine entrance corresponding to a magazine slot of the lower receiver; and a hammer entrance slot for a hammer of a trigger assembly of the semiautomatic lower receiver; and a bolt carrier engaging a co-axial firing pin. The bolt carrier reciprocates within the upper receiver under action of a handle. The handle guided within an upper receiver guide slot to rotate the bolt carrier with respect to the upper receiver between forward in-battery and forward out-of-battery positions and to slide lengthwise with respect to the upper receiver between the forward out-of-battery position and a rearward position. The bolt carrier comprises a hammer depressing protrusion which depresses the hammer when in the rearward position and a lengthwise hammer firing clearance slot coinciding with the hammer entrance slot when the bolt carrier is the forward in-battery position to allow clearance for the hammer to strike a rear end of the firing pin to detonate a round.

    Abstract: Cooperating mechanisms provide a reliable and robust semiautomatic firearm particularly suitable for firing necked rimfire cartridges. A reciprocating bolt assembly has delayed blowback and a firing pin block. Features prevent out-of-battery firing, when the bolt assembly is not fully engaged to the firing chamber or barrel face, a movable member within a bolt body functions as a blocking member that blocks the firing pin and prevents the firing pin from striking a cartridge. In embodiments, the firing pin has two stop portions that the movable member can engage depending on the cycle status of the firearm. A reverse cam mechanism associated with the firing pin blocking provides a resistance to and delays blowback. The bolt may interface with the necked rimfire cartridge using a undercut engagement on the forward end of the bolt. The semiautomaticfirearm also may incorporate one or both of a dual trigger arrangement as part of a trigger and firing mechanism with redundant hammer block and safety features, and trigger pull adjustment.

    Abstract: A readily replaceable bolt face for a firearm (10) with a movable slide (12) that strips a round from a magazine, extracts the spent round from the firing chamber and then ejects the round from the firearm by means of an ejector. A bolt face insert (32) has an external configuration that is common to a range of calibers, but with a bolt face side (66) designed to fit the rim of a specific caliber or calibers having the same rim dimension. The insert may be replaced to fit a different caliber without replacing the slide. The bolt face insert is provided with a slot (62) for the ejector and a groove (60) to accept an extractor for the specified caliber.

    Abstract: A muzzle brake device includes a main body having a receiver opening, a discharge opening, a central bore, and a plurality of discharge channels extending outward from the central bore at locations between the receiver opening and the discharge opening. A plurality of raised inlet members are disposed along the central bore and are in communication with the plurality of discharge channels. A separation distance between the channels is complementary to the length of the projectile to which the weapon on which the device is attached, and each of the discharge channels are arranged to emulate the vane of a turbine engine, so as to produce a mechanical force that counteracts the recoil of the weapon to which the device is attached.

    Abstract: The invention relates to a possible embodiment of an automatic pistol. The inventive pistol comprises a fixed barrel and a movable lock. Said pistol lock consists of two individual elements embodied in such a way that they can move with respect to each other and interact each with other. The first element of the lock is embodied in such a way that it is engageable with the barrel after departure thereof from the extreme front position at a certain distance. The second element of the lock is embodied in such a way that it can interact with a propellant charge with the aid of the first element, engage and disengage the first element with respect to the barrel. Before the first element being engaged with the barrel, the second element moves with acceleration with respect to the first element of the lock.
