Claims (36)

1. A handguard assembly for a firearm comprising:

an outer member disposed forward of an upper receiver of the firearm, the outer member comprising a rear cavity and a threaded portion;

a barrel nut disposed within the rear cavity; and

at least one alignment member,

wherein the at least one alignment member contacts both the outer member and the upper receiver for alignment.

2. The handguard assembly of claim 1 , wherein the outer member comprises a polymer material.

3. The handguard assembly of claim 1 , wherein the at least one alignment member comprises two alignment members.

4. The handguard assembly of claim 3 , wherein the two alignment members are connected to one another using a plurality of fasteners that pass through the outer member.

5. The handguard assembly of claim 3 , wherein the two alignment members are identical.

6. The handguard assembly of claim 1 , wherein the threaded portion comprises an insert that is a separate component from the outer member.

7. The handguard assembly of claim 6 , wherein the insert is metallic and outer member comprises a polymer material.

8. The handguard assembly of claim 7 , wherein the insert is overmolded as a permanent component of the outer member.

9. The handguard assembly of claim 1 , wherein an outer surface of the barrel nut comprises a taper such that the aft-most portion of the outer surface has a larger dimension than other portions of the outer surface.

10. The handguard assembly of claim 1 , wherein the at least one alignment member is metallic and comprises a counterbored hole and a threaded hole.

11. A free float handguard assembly for a firearm comprising:

an outer member comprising a rear cavity;

a barrel nut disposed within the rear cavity; and

at least one alignment member disposed adjacent to an upper rail of the outer member, wherein:

the outer member comprises a threaded portion that is removably attached to the barrel nut; and

the at least one alignment member aligns the outer member relative to the firearm.

12. The free float handguard assembly of claim 11 , wherein the at least one alignment member contacts both the outer member and an upper receiver of the firearm for alignment.

13. The free float handguard assembly of claim 11 , wherein:

the at least one alignment member comprises a left alignment member and a right alignment member; and

the left alignment member and the right alignment member are identical.

14. The free float handguard assembly of claim 11 , wherein the threaded portion comprises an insert that is a separate component from the outer member.

15. The free float handguard assembly of claim 14 , wherein the insert is metallic and outer member comprises a polymer material.

16. The free float handguard assembly of claim 15 , wherein the insert is overmolded as a permanent component of the outer member.

17. The free float handguard assembly of claim 11 , wherein the outer member comprises a polymer material.

18. The free float handguard assembly of claim 11 , wherein the at least one alignment member comprises two alignment members.

19. The free float handguard assembly of claim 18 , wherein the two alignment members are connected to one another using a plurality of fasteners that pass through the outer member.

20. A free float handguard assembly for a firearm comprising:

an outer member comprising a rear cavity;

a barrel nut disposed within the rear cavity; and

at least one alignment member, wherein:

the at least one alignment member aligns the outer member relative to the firearm; and
