This is a complete long-stroke piston upper by PWS. It is barely used (less than 200 rounds). It has upgraded Radian Raptor-LT charging handle, POF Roller Cam Pin, and KVP ASR Compatible Muzzle Brake. No original box. It makes a perfect suppressor host. I'm willing to ship ($15 extra) or locally in Dallas/Mckinney region. Asking for $700. Text FoursixNine-288-6047.
