An apparatus and methods are provided for a handguard for optimizing the ergonomics and operation of a direct gas operated firearm. The handguard comprises an elongated cylinder having an opening to allow a barrel of the firearm to extend through the handguard. A lock assembly attaches the handguard to a barrel nut area of the firearm. The lock assembly includes locks threaded onto opposite ends of a drive screw such that tightening the drive screw engages the locks with the barrel nut area of the firearm. Each lock has an adjustable contact surface and a taper surface that mate with corresponding surfaces on the barrel nut area of the firearm. The locks improve the strength of the upper receiver, reduce bending forces on the upper receiver, and reduce the amount of torque required to mount the handguard onto the firearm.
Muzzle blasts of firearms may be reduced by using sound suppressors, such as “noise suppressors” and “silencers.” Use of ablative media, or “wetting,” is one way to reduce the signature of a suppressed shot. The ablative media absorbs energy from hot gases in the suppressor, thereby reducing the amount of energy expelled from the suppressor. Current approaches to wetting are often messy processes, and it can be difficult to keep ablative media in place during transport or carriage of the firearm. Another difficulty can be meting out an advantageous quantity of ablative media into the suppressor. Embodiments presented herein provide an apparatus and methods for improving the application and use of ablative media in firearm suppressors.
An apparatus and methods are provided for a bolt carrier that optimizes the operation of direct gas operated firearms.

The boss and the beveled ring are configured to reduce the tilt of the bolt carrier when in a battery position. Different diameters of the boss and the beveled ring cause the bolt carrier to seat advantageously in various positions within the receiver extension. The flutes allow air transfer into and out of the space between the proximal end and the receiver extension to prevent air pressure from hindering the reciprocating motion of the bolt carrier.
