Abrégé

A firearm includes a receiver. A bolt carrier is moveable relative to the receiver between a firing position and a rearward position. A hand guard is coupled to the receiver. A gas tube is disposed at least partially within and fixed relative to the hand guard. A handle assembly is at least partially disposed in the hand guard and is moveable between a forward position and a charging position. The handle assembly has a body and an elongated member extending from the body toward the bolt carrier. The elongated member is disposed about the gas tube and is movable relative to the gas tube between the forward and charging positions. The elongated member engages the bolt carrier to move the bolt carrier from the firing position to the rearward position when the handle assembly moves from the forward position to the charging position.

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.

Abrégé

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.

A firearm includes a receiver and a barrel connected to the receiver. A hand guard extends from the receiver and defines a hand guard bore. The receiver includes a threaded end and the hand guard includes a flange extending into the hand guard bore and abutting the receiver about the threaded end. A hand guard nut abuts the flange of the hand guard and threadedly engaging the threaded end of the receiver. The hand guard nut sandwiches the flange between the hand guard nut and the receiver for attaching the hand guard to the receiver. The hand guard includes a first hand guard portion and a second hand guard portion removably attached to the first hand guard portion. The second hand guard portion is slid from an assembled position to a disassembled position to expose the hand guard nut in the hand guard bore.

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. A bolt carrier is disposed in the bore and moves relative to the receiver along the longitudinal axis between a firing position and a rearward position with the bolt carrier defining at least one exhaust port transverse to the longitudinal axis. A shield defines an aperture aligned with the exhaust port for exhausting gases therethrough. The shield is longitudinally affixed to the bolt carrier and moves 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.

The present invention provides for a firearm including a buttstock defining a first bore extending along a longitudinal axis and a receiver coupled to the buttstock. The receiver defines a second bore extending substantially parallel to the longitudinal axis and in fluid communication with the first bore. The receiver also defines an ejection port transverse to the longitudinal axis. The firearm further includes a bolt carrier disposed in the second bore and moveable relative to the receiver along the longitudinal axis between a firing position and a rearward position. The firearm also includes an expulsion device at least partially disposed in the buttstock for flowing air through the first and second bores and out the ejection port as the bolt carrier moves between the firing and rearward positions.

Abrégé

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.
