摘要： A slide action conversion assembly for converting a gas operated rifle into a manually operated slide action rifle. The conversion assembly replaces the gas operating system of the rifle with a linkage assembly attached to the original bolt carrier at a rearward end and to a sliding handguard grounded to a replacement stationary handguard at forward end. The linkage reciprocates within one degree of freedom along a path parallel to the barrel in order to manually cycle the converted firearm. The conversion assembly further incorporates a sliding handguard locking mechanism to prevent manual cycling when the firearm is in battery.

摘要： In some embodiments, a trigger group comprises a trigger arranged to pivot on a trigger axis and a hammer arranged to pivot on a hammer axis. The hammer includes a cam surface. The hammer is moveable from a first position to a second position upon break of the trigger, and the cam surface contacts the trigger in the second position. Desirably, the cam is arranged to bias the trigger.

摘要： An action lock for a Modern Sporting Rifle pump action firearm is pivotably mounted within the lower receiver of the rifle and has a stop surface that engages a contact surface on the bolt carrier when the bolt carrier is in battery. A cam on the hammer or the trigger engages a cam surface on the action lock when the hammer is released by a pull of the trigger. Cam action rotates the action lock out of engagement with the bolt carrier, unlocking it and allowing the fore end grip to be pumped to cycle the action and extract and eject the spent casing and strip and chamber a new round.

摘要： A self-loading firearm or pistol has an operating lever which can be actuated by the thumb of the shooting hand in order to release the hammer from its cocked position as well as to release the breech mechanism retaining the block in an open position. The operating lever comprises two operating lever members, each of which is disposed on one side of the firearm and both lever members are rigidly and firmly interconnected such that one of the operating lever members can be actuated by the thumb of the shooter's hand whether it is the right hand or the left hand.

摘要： An automatic firearm having a bolt which recoils upon each shot and an additional mass mounted for sliding parallel to the bolt and fastened to the bolt by an amplifying lever which is pivotally mounted on the bolt by a transverse pin and which has a resting surface adapted to come into contact with a stop surface which is stationary at the start of the recoil of the bolt. The amplifying lever is H-shaped. The cross bar of the H constitutes the transverse axis of pivoting of the assembly of the lever and the two vertical uprights constitute two symmetrical unit amplifying levers operating in parallel each capable of assuring a proper fastening together of the bolt and the additional mass. The assembly of the amplifying lever has complete symmetry with respect to the central plane perpendicular to its axis of pivot and lends itself to continuation of the firing in case of the breaking of one of the unit amplifying levers. The amplifying lever has a resting surface directed toward the rear adapted, upon the start of the recoil of the bolt, to come into contact with a stop surface rigidly fastened to a fixed portion of the firearm so as to impart to the amplifying lever a tilting movement which has the effect of accelerating the additional mass towards the rear. The arrangement imparts to the resting surface and the stop surface the shape of cylindrical sections of the same radius of curvature, so that the resting surface and stop surface cooperate by area contact when the recoil movement of the bolt commences.
摘要翻译：一种具有螺栓的自动枪械，其具有在每次射击时反弹的螺栓，以及安装成用于平行于螺栓滑动并由螺栓紧固到螺栓上的附加质量块，其通过横向销枢转地安装在螺栓上的放大杆，并且具有适于与在螺栓反冲开始时静止的止挡表面接触。放大杆为H形。 H的横杆构成杠杆的组件的枢转的横向轴线，并且两个垂直立柱构成两个对称的单元放大杆，每个平行操作，能够确保螺栓和附加质量块的适当紧固在一起。放大杆的组件相对于垂直于其枢轴轴线的中心平面具有完全的对称性，并且在断开一个单元放大杆的情况下本身能继续点火。放大杆具有指向后部的搁置表面，其适于在螺栓的反冲开始时与刚性地紧固到枪支的固定部分的止动表面接触，以便将放大杆赋予倾斜具有加速附加质量朝向后方的作用的运动。该布置赋予了搁置表面和止动表面具有相同曲率半径的圆柱形部分的形状，使得当螺栓的反冲运动开始时，搁置表面和止动表面通过区域接触协作。

摘要： A system and method for providing true decocking mechanism into a 1911-style firearm is provided. A decocking lever, when pushed in one forward motion, automatically returns a cocked hammer to its resting position. The decocking lever initially pushes the firing pin forward, out of reach of the hammer, and then pushes against the sear to release the hammer in its typical fashion.

摘要： A bolt catch assembly including a bolt engagement leg, a sliding member engagement leg, a contact member and an arrangement for enabling the bolt catch assembly to pivot about a pivot axis. The bolt engagement leg is configured for engaging a bolt of a firearm to hold the bolt in an open position. The sliding member engagement leg is connected to the bolt engagement leg. The contact member resiliently mounted on the sliding member engagement leg. The contact member is configured for being displaced between a static position and a displaced position whereby a catch engagement force is generated in response to the contact member being moved from the static position toward the displaced position. The arrangement for enabling the bolt catch assembly to pivot is disposed between the bolt engagement leg and the sliding member engagement leg thereby enabling the bolt engagement leg and the sliding member engagement leg to be pivoted in unison about the pivot axis of the bolt catch assembly.
