摘要： A bolt stop actuator is disclosed. The actuator may include a lift arm, a first leg extending from a point proximate to an end of the lift bar and generally perpendicular therefrom, a second leg extending in the same direction from the lift bar as the first leg, and a projection extending from the lift bar and configured to contact a follower of an empty magazine when the bolt stop actuator is assembled into a firearm. Neither the first leg, nor the second leg, include apertures positioned distal to the lift arm.

摘要： A modified AK-style rifle including a receiver body with a back end having a first threaded cylindrical cavity and a second cylindrical cavity located below the first threaded cylindrical cavity. A lower portion below the first threaded cylindrical cavity has a width that is narrower than the upper receiver section to allow for passage of a pair of parallel and opposing telescoping bars on each side. A trunnion is connected to the receiver front end and an ambidextrous bolt stop is attached to the receiver body. A removable stock is coupled to the first threaded cylindrical cavity. A first bolt carrier rail is attached to a first side wall of the receiver body and a second bolt carrier rail is attached to a second side wall of the receiver body. A bolt carrier slidingly bears on the first bolt carrier rail and the second bolt carrier rail. A gas block includes a short stroke gas piston aligned with the bolt carrier section.

摘要： A receiver for a firearm and a method of disposing the receiver to prevent automatic reloading and/or trigger reset of a firearm are disclosed. A blocking mechanism is moveable between an upward and a downward position and the blocking mechanism is in the downward position when the firearm is in battery. The blocking mechanism automatically moves to the upward position after a round is fired and the blocking mechanism prevents automatic reloading and/or trigger reset of the firearm when in the upward position.

摘要： A handheld finger activated semi-automatic arm may include a barrel, a trigger, a moveable gun bolt and a trigger reset mechanism. The trigger reset mechanism may use rigid mechanical contact between the trigger and the gun bolt during an earliest portion of the operating cycle. The trigger may be blocked from depression by the gun bolt up to 99% of the operating cycle.

摘要： A bolt hold open (BHOA) catch assembly configured for operating with rimfire ammunition for use with a firearm including a receiver with an exposed receiving chamber. A BHOA housing is supported upon the lower receiver in communication with a receiver chamber in communication with a bolt assembly. A catch is supported in elevatable fashion relative to an end of the actuator housing and an end most and downward extending structural portion of the elevatable catch is capable of being manipulated by an externally configured and toggled bolt catch so that an inner pivoting end portion thereof engages the structural portion to raise the BHOA supported catch into contact with a forwardly traveling bolt, such as upon release of a previously retracted charging handle. The BHOA catch can alternatively be actuated upwardly by a suitably configured follower associated with an attachable and cartridge holding magazine, this again following a last shot hold open protocol.

摘要： A cam pin system, includes a cam pin comprising a first cylindrical portion having a first length and a first diameter and a second cylindrical portion concentric with the first cylindrical portion and having a second diameter larger than the first diameter, the second cylindrical portion comprising a through-hole to accommodate the passage of a firing pin. The system includes an end plate detachably connected to the first cylindrical portion of the cam pin, a cylindrical bushing encircling the first cylindrical portion and having an outside diameter approximately equal to the second diameter and a bushing length approximately equal to the first length, and lubricant between the cylindrical bushing and the first cylindrical portion. The cam pin system is configured so that the cylindrical bushing can rotate freely about the first cylindrical portion.

摘要： An arrresting pin having a recessed circumferential section is inserted in the frame of the gun. A pin locking spring is biased into the mentioned recess. This locking spring prevents the arresting pin from falling out of the frame. A simple rotation of the arresting pin moves the locking spring out of the way, allowing an easy disassembling. The arresting pin includes further a planar jacket section, co-operating with a corresponding abutment surface at the slide for limiting the travel during the recoil of the slide.
