Convert your direct impingement AR15 carbine to a gas piston system with this conversion kit. Piston systems operate cleaner due to hot gasses being diverted at the gas block instead of the upper receiver. The piston is hard chrome plated and is removable from the front of the gas block. The one piece bolt carrier has an integral impingement key for maximum strength. Gas block has an on and off setting for use with a suppressor, or remove the piston and set the gas system to off for use with our .22 conversion system. Fits only carbine-length ARs with a .750" diameter barrel.
