Abstract

Provided is a firearm, comprising a receiver; a barrel; an upper handguard, a lower handguard, an upper barrel clamp and a lower barrel clamp, configured to be affixed to the receiver, wherein the upper barrel clamp and the lower barrel clamp are configured to be fastened together, affixing the upper barrel clamp and the lower barrel clamp to the barrel at a back-end of barrel; and wherein the upper handguard and lower handguard slide onto and are configured to be affixed to the upper barrel clamp and the lower barrel clamp, thus affixing the upper handguard and the lower handguard to both the barrel and the receiver such that the upper and lower handguards attach to the barrel solely at the back-end of the barrel.

Claims

1. A firearm, comprising:

a receiver;

a barrel; and

a handguard;

an upper barrel clamp;

a lower barrel clamp, configured to be affixed to the receiver;

a first plurality of holes in the lower barrel clamp; and

a wedge clamp configured to affix the handguard to the barrel and the receiver, the wedge clamp comprising;

a draw wedge, the draw wedge comprising a second plurality of holes, each hole of the second plurality of holes having a corresponding hole in the first plurality of holes; and

a floating wedge, the floating wedge comprising a third plurality of holes, each hole of the third plurality of holes with a corresponding hole in the first and second plurality of holes;

a plurality of fasteners corresponding to the first, second and third plurality of holes such that each fastener passes through corresponding holes in the first, second and third plurality of holes to affix the lower barrel clamp, the draw wedge and the floating wedge to the receiver such that the wedge clamp expands within the receiver;

wherein the upper barrel clamp and the lower barrel clamp are configured to be fastened together, affixing the upper barrel clamp and the lower barrel clamp to the barrel at a back-end of the barrel.

2. The firearm of claim 1, further comprising:

a guide tube; and

a guide tube support affixed to the handguard, configured such that the guide tube is supported in and sealed with respect to the guide tube support without restricting small movements of the guide tube within the guide tube support.

3. The firearm of claim 2, the firearm further comprising a gas block and the guide tube further comprising:

an alignment slot configured to prevent the guide tube from rotating with respect to the handguard; and

a plurality of venting holes configured such that hot gas from the gas block is directed towards the barrel and away from the handguard.

4. The firearm of claim 1, the handguard further comprising a plurality of ventilation holes.

5. The firearm of claim 1, wherein the firearm is a rifle.

6. A apparatus for holding a firearm, comprising:

a handguard;

an upper barrel clamp; and

a lower barrel clamp, configured to be affixed to a receiver of the firearm,

a first plurality of holes in the lower barrel clamp; and

a wedge clamp configured to affix the handguard to a barrel of the firearm and the receiver, the wedge clamp comprising;

a draw wedge, the draw wedge comprising a second plurality of holes, each hole of the second plurality of holes having a corresponding hole in the first plurality of holes; and

a floating wedge, the floating wedge comprising a third plurality of holes, each hole of the third plurality of holes with a corresponding hole in the first and second plurality of holes;

a plurality of fasteners corresponding to the first, second and third plurality of holes such that each fastener passes through corresponding holes in the first, second and third plurality of holes to affix the lower barrel clamp, the draw wedge and the floating wedge to the receiver such that the wedge clamp expands within the receiver;

wherein the upper barrel clamp and the lower barrel clamp are configured to be fastened together, affixing the upper barrel clamp and the lower barrel clamp to the barrel of the firearm at a back-end of the barrel.

7. The apparatus of claim 6, further comprising:

a guide tube; and

a guide tube support affixed to the handguard, configured such that the guide tube is supported in and sealed with respect to the guide tube support without restricting small movements of the guide tube within the guide tube support.

8. The apparatus of claim 7, the firearm further comprising a gas block and the guide tube further comprising:

an alignment slot configured to prevent the guide tube from rotating with respect to the handguard; and

a plurality of venting holes configured such that hot gas from the gas block is directed towards the barrel and away from the handguard.

9. The apparatus of claim 6, the handguard further comprising a plurality of ventilation holes.

10. The apparatus of claim 6, wherein the apparatus is configured to be employed with a rifle.
