摘要： A small firearm includes: a receiver; a barrel including a barrel bore axis; an action including a bolt head; and a guide surface, the receiver being configured for (i) at least indirectly receiving the barrel including a locking mechanism area, a chamber, a guide area, and a muzzle arranged successively in the longitudinal direction, and (ii) at least indirectly receiving the action movably arranged within the receiver along the longitudinal direction from an open position to a closed position, the guide surface, which is within a locking space, being configured such that at least one of (i) an entry of a cartridge case under an influence of a torque during a movement of the action from a closed position to an open position is limited due to an interaction of an ejector and an extractor and (ii) an exit of the cartridge case is favored.

摘要： Disclosed herein are bolt carrier movement mechanisms that offer a higher ratio of bolt carrier applied force to user applied bolt action operating force. Such bolt carrier movement mechanism may comprise a bolt carrier, an impingement body, a primary extraction leverage member, and an action control structure coupler. The impingement body has at least one impingement surface. The primary extraction leverage member has a coupler mounting portion, an impingement member portion, and a bolt carrier mounting portion. The primary extraction leverage member is engaged at the bolt carrier mounting portion of the bolt carrier. The impingement member portion of the primary extraction leverage member is adjacent to the at least one impingement surface of the impingement body and includes at least one impingement member. The action control structure coupler is pivotably engaged with the coupler mounting portion of the primary extraction leverage member.

摘要： A non-metallic sleeve device adapted for use with a firearm bolt. The non-metallic sleeve is generally durable, heat resistant, and generally nonmalleable. The firearm bolt may be used on a bolt action, semiautomatic, or automatic firearm. There are two steel ends of the bolt each with an inner portion and an outer portion, said inner portion having a reduced diameter and screw threading thereon. A non-metallic sleeve, comprising a material such as carbon fiber, may be epoxied in position onto the screw threading. The result is reduced weight of the firearm bolt.

摘要： Provided herein are bolt carriers, firearms, and related methods, devices, and assemblies. A bolt carrier for a firearm of an example embodiment includes a cam slot configured to receive a cam pin of a bolt, the cam slot defining a cam path along which the cam pin is configured to travel, the cam path comprising a locked dwell, an unlocked dwell, and a transition section disposed between the locked dwell and the unlocked dwell, wherein the locked dwell defines a portion parallel to a first axis of the bolt carrier that is greater than 0.070 inches long.

摘要： Firearms including a secured firing pin retaining pin, the firearms having a barrel, a sliding block, a bolt head, a firing pin with a flange-like collar, a firing pin retaining pin with a safety device, and a weapon median plane. For facilitating handling, it is provided that the firing pin retaining pin is slidably mounted normally to the weapon median plane in a retaining bore, that it is designed as one piece and to be rotationally symmetrical with a head and a pin end and has two annular grooves. A locking pin mounted in a spring-loaded manner in the sliding block is designed such that, depending on the position of the firing pin retaining pin in the retaining bore, it can optionally engage in one of the annular grooves, which correspond to a holding position and a release position for the firing pin, respectively.

摘要： An improved bolt and bolt carrier with integral gas key having an extension nozzle threadedly secured and pinned to the gas key for use with a direct gas operated firearm is provided. The extension nozzle is designed to receive a portion of the host firearm's gas operating system. The firing pin retaining pin is oriented so as to expose its widest profile to the firing pin's annular flange, increasing its service life. The bolt has a plurality of lugs extending from its forward end. The extractor recess is constructed so that the face of the bolt is round and the adjacent lugs fully supported. The extractor engages approximately 17% more of a seated ammunition cartridge's rim as compared to the prior art AR15/M16 extractor. The result is an improved bolt and bolt carrier which provides for increased operational reliability.

摘要： A firearm system includes a bolt carrier with an internal cavity, a piston disposed within the internal cavity, a forward configuration where the piston is in a forwardmost position relative to the bolt carrier, and an aft configuration where the piston is in a rearmost position relative to the bolt carrier. The piston slides forward and aft relative to the bolt carrier. In the forward configuration, the entire piston remains disposed within the bolt carrier.

摘要： Retaining devices securable on firearms are selectively operable to engage and retain a bolt assembly in a substantially-fixed position for an indeterminate period of time. The retaining devices include a mounting plate securable to the receiver and a retention pin that extends through a passage in the mounting plate. The retention pin extends axially between first and second ends that project outwardly beyond the mounting plate. The retention pin is supported on the mounting plate for axial displacement between a first pin position and a second pin position. In the first pin position, the second end of the retention pin engages and retains the bolt assembly in a substantially-fixed position relative to the receiver. In the second pin position, the second end of the retention pin is disengaged from the bolt assembly.

摘要： A rotating bolt firearm may be configured to fire a .308 cartridge. However, the firearm may have a reduced weight in comparison to standard .308 rifles. The firearm may have many components typically used in a .223 rifle. The firearm may include a barrel extension with an extractor gap, which allows a .308 bolt to fit within a .223 sized barrel extension. The firearm may comprise an elongated magazine well in comparison to a .223 mil-spec rifle. The firearm may weigh less than 6.8 pounds with a 16-inch barrel, or less than 6.3 pounds with a 10.5 inch barrel.
