Abstract

Embodiments of the disclosure can include systems, methods, and apparatuses for installing a hand guard on a firearm. In some embodiments, a method of installing a hand guard on a firearm can be provided. The firearm includes a barrel, a barrel nut, and a delta ring. The delta ring is refracted away from the barrel nut. A number of hand guard members are positioned about the barrel. An annular groove formed between a forward plate and a rear plate associated with each hand guard member is mated with a portion of a flange of the barrel nut. The flange is secured within the annular groove of at least one hand guard member. The delta ring is advanced over a portion of some or all the hand guard members.

Claims (44)

1. A hand guard assembly for installing on a firearm, the firearm having a barrel nut, the barrel nut having a flange, the hand guard assembly comprising:

a plurality of hand guard members;

a coupling mechanism configured to couple at least some of the hand guard members together; and

a securing mechanism configured to secure at least one of the hand guard members to the barrel nut, the securing mechanism applying a clamping force in a direction generally parallel to a longitudinal axis of the firearm, the securing mechanism comprising:

a connector comprising a forward plate, a rear plate, and an annular groove formed between the forward plate and the rear plate, the annular groove being sized and shaped to receive at least a portion of the flange; and

a clamping device adapted to clamp the forward plate and the rear plate about at least a portion of the flange.

2. The hand guard assembly of claim 1 , wherein the plurality of hand guard members comprise an upper hand guard member and a lower hand guard member.

3. The hand guard assembly of claim 1 , wherein each hand guard member is shaped so that an interior surface of the hand guard member is spaced apart from a barrel of the firearm when the hand guard member is positioned adjacent to the firearm.

4. The hand guard assembly of claim 1 , wherein the coupling mechanism comprises:

a passageway through a first of the hand guard members;

a threaded opening within a second of the hand guard members; and

a fastener that can be passed through the passageway into the threaded opening to secure the first of the hand guard members to the second of the hand guard members.

5. The hand guard assembly of claim 1 , wherein the clamping device comprises:

a threaded opening formed through the connector; and

a clamping screw positioned in the threaded opening.

6. The hand guard assembly of claim 5 , wherein the threaded opening extends in a direction generally parallel to the longitudinal axis.

7. The hand guard assembly of claim 5 , wherein the forward plate and the rear plate are clamped together about at least a portion of the flange as the clamping screw is threaded in the threaded opening.

8. A method of installing a hand guard on a firearm, the firearm having a barrel, a barrel nut, and a delta ring, the method comprising:

retracting the delta ring from the barrel nut;

positioning one or more hand guard members about the barrel, wherein an annular groove formed between a forward plate and a rear plate of each hand guard member mates with at least a portion of a flange of the barrel nut;

advancing the delta ring over at least a portion of some or all of the hand guard members; and

securing the flange within the annular groove of at least one hand guard member using a clamping device adapted to clamp the forward plate and the rear plate about at least a portion of the flange.

9. The method of claim 8 , wherein positioning one or more hand guard members about the barrel forms an air gap about the barrel.

10. The method of claim 8 , wherein securing the flange within the annular groove comprises applying a clamping force about the flange using the clamping device, the clamping force being applied in a direction that is generally parallel to a longitudinal axis of the firearm.

11. The method of claim 8 , the firearm comprising an existing hand guard held in place on the barrel between the barrel nut and the delta ring, and the method further comprising removing the existing hand guard from contact with the barrel nut.

12. The method of claim 8 , further comprising coupling at least some of the hand guard members to adjacent hand guard members.

13. An apparatus for installing a hand guard on a firearm, the firearm having a barrel nut, the barrel nut having a flange, the apparatus comprising:

a securing mechanism configured to secure a hand guard member to the barrel nut, the securing mechanism applying a clamping force in a direction generally parallel to a longitudinal axis of the firearm, the securing mechanism comprising:

a connector comprising a forward plate, a rear plate, and an annular groove formed between the forward plate and the rear plate, the annular groove being sized and shaped to receive at least a portion of the flange; and

a clamping device adapted to clamp the forward plate and the rear plate about at least a portion of the flange.

14. The apparatus of claim 13 , wherein the hand guard member comprises an upper hand guard member or a lower hand guard member.

15. The apparatus of claim 13 , wherein the hand guard member is shaped so that an interior surface of the hand guard member is spaced apart from a barrel of the firearm when the hand guard member is positioned adjacent to the firearm.

16. The apparatus of claim 13 , wherein the clamping device comprises:

a threaded opening formed through the connector; and

a clamping screw positioned in the threaded opening.

17. The apparatus of claim 16 , wherein the threaded opening extends in a direction generally parallel to the longitudinal axis.

18. The apparatus of claim 16 , wherein the forward plate and the rear plate are clamped together about at least a portion of the flange as the clamping screw is threaded in the threaded opening.

19. The apparatus of claim 13 , further comprising:

one or more additional hand guard members; and

a coupling mechanism configured to couple at least some of the hand guard members together.

20. The apparatus of claim 19 , wherein the coupling mechanism comprises:

a passageway through a first of the hand guard members;

a threaded opening within a second of the hand guard members; and

a fastener that can be passed through the passageway into the threaded opening to secure the first of the hand guard members to the second of the hand guard members.
