Abstract
A hand guard installation mechanism for securing a hand guard over the barrel of a firearm includes a tapered locking element that extends at least partially through the hand guard and interfaces with a surface of the barrel nut of the firearm. A fastener mates with the locking element, drawing the locking element at least farther into the hand guard and against the surface of the barrel nut. As the locking element is drawn against the barrel nut, the hand guard is tightened against the barrel nut such that the hand guard is secured in place against the receiver of the firearm.
Claims26
A hand guard attachment mechanism for mounting a hand guard to a receiver of a firearm, the hand guard attachment mechanism comprising:
- a barrel nut having a proximal end adapted to be mounted to the receiver of the firearm, a distal end configured to receive and mount the barrel of the firearm to the receiver, and a shoulder section defined between the proximal and distal ends;
- at least one locking element comprising a body having a tapered section at least partially received through a crosswise passage defined through a portion of the hand guard, wherein the at least one locking element is adapted to interface with the shoulder section of the barrel nut, the body of the at least one locking element further including a bore extending at least partially therethrough;
- and
- a fastener for extending into the crosswise passage of the hand guard and for being at least partially received within the bore of the at least one locking element;
- wherein at least the fastener and the at least one locking element are cooperatively configured so that engagement of the fastener within the bore of the at least one locking element draws the tapered section of the at least one locking element at least farther into interfacing engagement with the shoulder section of the barrel nut;
- and
- wherein the barrel nut comprises an outer surface for mating with an inner surface of the hand guard.
4 more elements
A firearm comprising:
- a receiver;
- a barrel mountable to the receiver;
- a hand guard releasably mountable to the receiver, the hand guard including at least one crosswise passage extending at least partially through a portion of the hand guard, and a lengthwise passage extending along a longitudinal axis of the hand guard and through which the barrel is at least partially received, wherein the crosswise passage extends crosswise to the longitudinal axis of the hand guard, and the hand guard further comprises an opening between the crosswise passage and the lengthwise passage;
- a barrel nut configured for at least partially mounting the barrel to the receiver;
- and
- at least one locking element at least partially received within both the crosswise passage and the opening between the crosswise passage and the lengthwise passage, the at least one locking element comprising a tapered section that is wedged between portions of the hand guard and the barrel nut for providing at least one mounting force between the hand guard and the barrel nut, wherein the fastener, the hand guard and the barrel nut are cooperatively configured so that the at least one mounting force comprises a substantially axial mounting force between the hand guard and the barrel nut.
3 more elements
A hand guard for a firearm, the hand guard comprising:
- a body having opposite proximal and distal ends;
- a lengthwise passage extending along a length of the hand guard and configured to at least partially receive a barrel of the firearm;
- at least one crosswise passage extending through a portion of the body of the hand guard, the crosswise passage extending crosswise to the length of the hand guard, the crosswise passage having openings on opposite outer sides of the body of the hand guard and configured for at least partially receiving a fastener assembly therein;
- and
- an opening defined between the crosswise passage and the lengthwise passage sufficient to enable at least a portion of the fastener assembly to project into the lengthwise passage for securing the hand guard to the firearm.
2 more elements
A method for mounting a hand guard to at least a barrel nut, comprising:
- causing relative movement between the hand guard and the barrel nut so that the barrel nut is at least partially received in a lengthwise passage of the hand guard;
- and
- providing at least one mounting force between the hand guard and the barrel nut while the barrel nut is at least partially positioned in the lengthwise passage of the hand guard, wherein:
- the at least one mounting force comprises a substantially axial mounting force between the hand guard and the barrel nut, and the substantially axial mounting force is directed in a direction that extends along the lengthwise passage of the hand guard, and
- the providing of the at least one mounting force between the hand guard and the barrel nut is comprised of wedging between the hand guard and the barrel nut, so that the wedging at least partially causes the axial mounting force between the hand guard and the barrel nut.
2 more elements
A hand guard attachment mechanism for mounting a hand guard to a firearm, the hand guard attachment mechanism comprising:
- a mounting structure comprising a shoulder;
- at least one locking element comprising a body having a tapered section at least partially received in a crosswise passage defined through a portion of the hand guard, wherein the at least one locking element is adapted to interface with the shoulder of the mounting structure, the body of the at least one locking element further including a bore extending at least partially therethrough;
- and
- a fastener for extending into the crosswise passage of the hand guard and for being at least partially received within the bore of the at least one locking element;
- wherein at least the fastener and the at least one locking element are cooperatively configured so that engagement of the fastener within the bore of the at least one locking element draws the tapered section of the at least one locking element at least farther into interfacing engagement with the shoulder of the mounting structure;
- and
- wherein the mounting structure comprises an outer surface for mating with an inner surface of the hand guard.
