Abstract: One aspect of the present disclosure is directed to a crush washer for a firearm that comprises a ring of material about a center axis having an inner surface towards the center axis and an outer surface away from the center axis, and at least one groove in the inner surface or outer surface. The groove forms: a first flange having an inner surface and an outer surface with a thickness therebetween; a second flange having an inner surface and an outer surface with a thickness therebetween; and a bridge connecting the first flange and the second flange, the bridge having an inner surface and an outer surface with a thickness therebetween. In an undeformed state, the inner surface of the first flange is adjacent to, but spaced apart from, the inner surface of the second flange. In a deformed state, the inner surface of the first flange is closer to the inner surface of the second flange compared to the undeformed state.

Abstract: A firearm bolt assembly for a self-loading firearm has an elongated frame defining a frame axis, a bolt connected to a forward end of the frame, a plurality of separate weights connected to the frame, and the weights being movable at least slightly with respect to the frame and to each other for movement along the axis. There may be a resilient spacer element between adjacent weights. There may be a resilient spacer element between one of the weights and a portion of the frame. The spacer element may be an O-ring. The weights may be connected to a rear portion of the frame. The weights may be tubular bodies each defining a bore. A portion of the frame may be received within the bore. The frame may define a rear portion having a first diameter, and a flange forward of the rear portion having a larger second diameter.

Abstract: A captured spring assembly for a firearm has a rod having a forward and rearward ends, a movable buffer that defines an aperture that receives the forward end of the rod and is operable to reciprocate between a forward battery position and a rearward retracted position, a coil spring that encompasses the rod, wherein the forward end of the rod has a limit element having a head that is larger in diameter than the rod, wherein the buffer has an internal limit element that is larger in diameter than the rod, and wherein the internal limit element has at least one portion that is smaller in diameter than the limit element head, but also larger in diameter than the rod. There may be a spring stop attached to the rearward end of the rod that is large enough for the spring to bear against and the buffer to strike against.

Abstract: A trigger assembly comprising a housing adapted to mount a trigger, hammer and sear therein. The housing has an adjustment feature adapted to fixedly mount the housing within the trigger chamber portion of the firearm. The trigger assembly is particularly conducive for an AR-15 type rifle and the various sear engagement surfaces are adapted to be adjustable irrespective of the various dimensions and tolerances of the underlying firearm.
