摘要： A firearm including a barrel having a breech and a muzzle defining a length of the barrel is disclosed. The firearm includes a hand guard having a first end and a second end with a front sight is attached to at least one of the barrel adjacent the muzzle and the second end of the hand guard. A housing is coupled to the front sight and defines a chamber having a piston disposed therein and movable between static and displaced positions. A receiver is coupled to the first end and a bolt carrier is disposed within the receiver and moveable between firing and rearward positions. A carrier key is attached to the bolt carrier and moves concurrently with the bolt carrier and a rod is permanently affixed to the carrier key and extends to a distal end with the piston engaging the distal end when moving to the displaced position.

摘要： A firearm comprising a receiver including a threaded end with the receiver extending along an axis and a hand guard having an exterior surface and defining a hand guard bore along the axis with the exterior surface terminating at a mating surface disposed about the threaded end. The firearm additionally includes a barrel disposed within the hand guard bore and abutting the threaded end and a nut abutting the barrel and engaging the threaded end of the receiver to secure the barrel to the receiver. The firearm further including a securing device with the exterior surface of the hand guard defining an engagement area providing access into the hand guard bore and the securing device interfacing with the engagement area and extending into the hand guard bore to abut the nut and securely mount the mating surface of the hand guard to the receiver.

摘要： The present invention provides for a firearm having a receiver defining a bore with the receiver extending along a longitudinal axis. The receiver defines an ejection port transverse to the longitudinal axis with the bore defining an inner surface. The firearm further includes a bolt carrier disposed in the bore and moveable relative to the receiver along the longitudinal axis between a firing position and a rearward position. The firearm also includes a shield longitudinally affixed to the bolt carrier and movable with the bolt carrier as a unit between the firing and rearward positions along the longitudinal axis with the shield blocking the ejection port when in the firing position and the shield sliding along the inner surface away from the ejection port when moving to the rearward position in conjunction with the bolt carrier.

摘要： A firearm includes a receiver and a bolt carrier disposed in the receiver. The bolt carrier is moveable between a firing position and a rearward position. A rod is fixed relative to the bolt carrier and a hand guard is coupled to the receiver about the rod. A handle assembly is slideably supported by the hand guard and is moveable toward the receiver to define a charging motion and away from the receiver to define a forward assist motion. The handle assembly receives the rod during both of the charging and forward assist motions. An arm is coupled to the base and is moveable between a disengaged position spaced from the rod and an engaged position abutting the rod. When the arm is in the engaged position, the handle assembly is moved to move the rod and the bolt carrier in either of the charging and the forward assist motions.
