Bushmaster Gas Piston 90294

The Bushmaster Gas Piston System Rifles bring new levels of reliability to the “AR” type rifle platform by eliminating carbon build up, gas leaks and heat within the Upper Receiver. The Gas Piston System operates by tapping gas pressure off the barrel much like the systems found on AK-47s and FALs * Functions with a wider range of ammunition - less gas pressure - lower cyclic rate * Offers improved reliability and control - with cleaner operation and reduced recoil * Keeps carbon build up and powder residue from reaching - and fouling the Upper Receiver and Bolt Carrier * A Detented Plug in the Gas Block allows easy cleaning of the Systems’ Hard Chrome Plated Piston
