Abstract

Embodiments of the invention can include systems and methods for installing a hand guard on a firearm. In 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 retracted away from the barrel nut. A number of hand guard members are positioned about the barrel. An annular groove 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 (49)

1. A hand guard assembly for installing on a firearm, the firearm having a barrel nut with 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, wherein the securing mechanism comprises:

a connector adapted to associate at least one of the hand guard members with the barrel nut, wherein the connector is sized and shaped to mate with at least a portion of the flange; and

a clamping device comprising a threaded opening formed through the connector and a set screw positioned in the threaded opening, wherein the clamping device is adapted to clamp the connector against the flange of the barrel nut.

2. The hand guard assembly of claim 1 , wherein at least some of 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 sized so that an interior surface of the hand guard member is spaced apart from 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 connector comprises a forward rim, a rearward rim, and an annular groove positioned between the forward rim and a rearward rim, the annular groove being sized and shaped to mate with at least a portion of the flange; and

the clamping device is adapted to clamp the flange against the rearward rim.

6. The hand guard assembly of claim 1 , wherein the threaded opening extends in a direction generally parallel to the longitudinal axis.

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

a plurality of hand guard members, wherein at least some of the plurality of hand guard members comprise an upper hand guard member and a lower hand guard member, and wherein each hand guard member is sized so that an interior surface of the hand guard member is spaced apart from the firearm when the hand guard member is positioned adjacent to the firearm;

a coupling mechanism configured to couple at least some of the hand guard members together, 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; 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, wherein the securing mechanism comprises:

a connector adapted to associate at least one of the hand guard members with the barrel nut, wherein the connector is sized and shaped to mate with at least a portion of the flange; and

a clamping device comprising a threaded opening formed through the connector and a set screw positioned in the threaded opening, wherein the clamping device is adapted to clamp the connector against the flange of the barrel nut.

8. The hand guard assembly of claim 7 , wherein:

the connector comprises a forward rim, a rearward rim, and an annular groove positioned between the forward rim and a rearward rim, the annular groove being sized and shaped to mate with at least a portion of the flange; and

the clamping device is adapted to clamp the flange against the rearward rim.

9. The hand guard assembly of claim 7 , wherein the threaded opening extends in a direction generally parallel to the longitudinal axis.

10. A method for providing a hand guard assembly for installing on a firearm having a barrel nut, the method comprising:

providing a plurality of hand guard members;

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

manipulating a securing mechanism 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.

11. The method of claim 10 , wherein at least some of the plurality of hand guard members comprise an upper hand guard member and a lower hand guard member.

12. The method of claim 10 , wherein each hand guard member is sized so that an interior surface of the hand guard member is spaced apart from the firearm when the hand guard member is positioned adjacent to the firearm.

13. The method of claim 10 , 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.

14. The method of claim 10 , wherein the securing mechanism comprises:

a connector adapted to associate at least one of the hand guard members with the barrel nut; and

a clamping device adapted to clamp the connector against the barrel nut.

15. The method of claim 14 , the barrel nut having a flange, wherein:

the connector comprises a forward rim, a rearward rim, and an annular groove positioned between the forward rim and a rearward rim, the annular groove being sized and shaped to mate with at least a portion of the flange; and

the clamping device is adapted to clamp the flange against the rearward rim.

16. The method of claim 14 , the barrel nut having a flange, wherein:

the connector is sized and shaped to mate with at least a portion of the flange; and

the clamping device comprises a threaded opening formed through the connector and a set screw positioned in the threaded opening.

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