16" M4 Profile Barrel. Gas Piston systems operate cleaner then the direct gas impingement operating systems. With the piston system, the propellant gases that are being diverted at the gas block are now vented at the gas block, instead in the operating system of the upper receiver. Since the fouling from the gas system is not being vented in to the action of your firearm, it stays cooler and cleaner. Our system is designed around the short stroke piston operation. The piston pushes the anti tilt one piece carrier, which unlocks the bolt and allows the piston to return home while the bolt carrier continues to cycle independently.
The chrome plated gas piston is mounted in a solid one piece steel gas block attached to the barrel by pins. the Gas Block's 1913 Piccatinny rail is receiver height and requires a front sight designed to be mounted on the same plane as the rear sight. The dedicated, piston specific, anti-tilt bolt carrier is a one piece unit, machined with an integral piston impingement key (not a bolt on).
The piston gas block has a gas shut off setting for use with a suppressor to allow for maximum noise reduction. You must replace the crush washer with a peel washer if you plan to mount your suppressor on the original flash hider. Sights are not included with this model.
Includes one 30 round magazine and manual. Barrels are engraved CMMG WASP 5.56 NATO 1:9. Each firearm is head spaced and test fired before shipping.
