CMMG MOD4 SA Piston Ar15 Rifle .223/5.56

AimSurplus Guns & Ammunition

Middletown, OH - -(AmmoLand.com)- New CMMG MOD4 SA .223/5.56 Gas Piston Rifles. Gas Piston systems operate cleaner then the direct gas impingement operating systems. With the piston system, the propellant gases that are being diverted by the gas block into the operating system, are instead vented at the gas block.

Since the fouling from the gas system is being vented, the action it stays cooler and cleaner. This system is designed around short stroke piston operation. The piston pushes the anti tilt one piece carrier, which unlocks the bolt and allows the piston to return while the bolt carrier continues to cycle independently. Item#CMMG-FM4LEPII

Brownells.com

Brownells.com - -(AmmoLand.com)-Rugged, semi-auto receiver made from a high-quality forging is built to handle the hard use and abuse of tactical and competitive shooting.

Forged from 7075 T6 aluminum alloy, for an extra margin of strength and rigidity over standard 6061 alloy receivers, before precision machining to final mil-spec dimensions.

Available as a Stripped lower receiver ready for a full custom build, or Complete and fully assembled including pistol grip and trigger group, with a choice of ambi safety selector or standard, left-side mounted selector.

CMMG’s engineers designed custom fixtures for final grinding of 10 separate contact surfaces on the trigger, disconnector, and hammer to ensure a crisp, precise release.

Proprietary bronze bushings on trigger and hammer pins reduce friction for a consistent, ultra-smooth pull and exceptionally fast locktime.

Rounded, low-mass hammer further speeds locktime and reduces wear on contact surfaces.

Trigger is function tested before lower leaves factory; compatible with .22 LR conversions.
