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 damp 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, the handguard comprising;

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.

2. The firearm of claim 1, further comprising a wedge clamp configured to affix the handguard to the barrel and the receiver.

3. The firearm of claim 2, further comprising:

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

the wedge clamp comprising;
