摘要： A trigger unit for a firearm, including a hammer rotatable about a hammer axis and prestressable by a hammer spring, a trigger lever rotatable about a trigger axis, the trigger lever has a trigger and a trigger rear, which receives at least one interrupter. A sear is rotatably mounted about a sear axis and prestressable by a sear spring. The sear axis and the trigger axis coincide, and the sear has a bearing recess for receiving and limited rotation about a disconnector axis of a disconnector pivot formed on the underside of the disconnector, the bearing recess being formed surrounding the disconnector pivot at least partially in the direction of rotation about the disconnector axis.

摘要： A firearm spring compression tool includes a base configured for anchoring the tool in a magazine well. A yoke is mounted on the base and includes a pair of arms configured for capturing a delta ring (“D-ring”) or other component on a firearm. An actuator is rotatably mounted on the yoke and is rotatable between a first, placement position for placing the yoke over the uncompressed D-ring and a second, compressed, release position. With the actuator in its second position, the D-ring is compressed whereby a handguard component of the firearm is released for removal in connection with a firearm servicing procedure.

摘要： A firearm includes a frame, a slide assembly, an actuator, a bolt assembly, and an adjuster. The slide assembly includes a threaded bore, the slide assembly releasably and slidably coupled to the frame. The actuator includes a body and an extension, the extension protruding from the body. The bolt assembly includes a catch. The adjuster includes a first end, a second end, and a plurality of threads. The first end includes an interface configured to accommodate the extension of the actuator. The plurality of threads are disposed between the first end and the second end. The plurality of threads are configured to interface with the threaded bore of the slide assembly such that rotation of the adjuster within the threaded bore of the slide assembly by the actuator translates the bolt assembly and thereby facilitates firing ammunition having different casing lengths.

摘要： An ambidextrous lower receiver for an automatic rifle is an apparatus that allows a rifle bolt of an upper receiver that is mounted on the apparatus to be manipulated from either side of the automatic rifle. The apparatus includes a lower-receiver body, a bolt catch button, a bolt catch lever, a pusher finger, and a length-adjustable pin. The lower-receiver body attaches with the upper receiver of an automatic rifle and connects a magazine and a pistol grip to the automatic rifle. The lower-receiver body positions the bolt catch button and the bolt catch lever. The bolt catch button releases and locks the bolt catch lever. The bolt catch lever releases and locks the rifle bolt of a corresponding upper receiver. The bolt catch button manipulates the bolt catch lever from the opposite side of the automatic rifle with the pusher finger and the length-adjustable pin.

摘要： A takedown pin system may be used for the processes of securing, semi-securing, and/or un-securing the rear connection points of firearm lower and upper receivers, for example, of an AR-15, with an option to maintain axial engagement of the pin to the receivers throughout two or more of the processes. An enhanced pin detent track allows pin rotation when axially-engaged in the receivers. A narrow pin body portion, for example, a recessed side surface portion or a narrow flange, cooperates with the pin hole and/or a slot in an upper receiver rear knuckle. Rotating the pin may locate the recess or flange to make room between the pin and the inner surface(s) of the upper receiver pin hole so the upper receiver can pivot slightly open from the lower receiver. A slot at the bottom of the rear knuckle hole may receive a flange of the takedown pin.

摘要： A slide assembly quick release pin and arm that secure a recoil assembly within a slide. The pin is inserted through a pair of apertures in a front portion of the slide and through a bore in the nose portion of the recoil assembly aligned between the apertures. As the pin secures the recoil assembly within the slide an arm attached to the end of the pin rests in a recess, flush to the body of the slide in a locked orientation. The pin arm is rotated from a locked orientation within the recess in the assembled configuration to an unlocked orientation out of the recess before the firearm is disassembled. Additionally, the arm acts as a handle for grasping and rotating to provide a mechanical advantage when a user is removing or inserting the pin into the apertures and bore.

摘要： A modified assembly configured for firearm capable of propelling ammunition is disclosed. The modified assembly, in some embodiments, includes a firing control unit (“FCU”) and a grip module. The FCU is a serialized trigger mechanism capable of initiating a directional object when a trigger of the FCU is pulled. The grip module, in some aspects, includes a hand grip, FCU housing, and rear stabilizing connector wherein the FCU housing is configured to house a removable FCU. The rear stabilizing connector, for example, is capable of coupling to a rear attachment for enhancing stability of the modified assembly. In alternative embodiments, the modified assembly further includes a slide assembly, barrel, barrel block, bolt, and return spring situated in the vicinity of the FCU for facilitating object launching process.

摘要： A bullpup conversion kit for a firearm including a lower receiver with a topside channel that partially receives an upper receiver of the firearm and a magazine well. The firearm includes a trigger pack with a removable trigger. A trigger bar assembly including a trigger bar, a front trigger mount, and a trigger shoe is received within the topside channel. The trigger bar extends along one side of the magazine well. The front trigger mount is disposed on a forward end of the trigger bar. The trigger shoe includes upper and lower ends. The upper end of the trigger shoe is pivotally coupled to the trigger pack in place of the removable trigger. The lower end of the trigger shoe is connected to a rearward end of the trigger bar by a pin. The lower receiver hinges away from the upper receiver about a front hook during disassembly.
