Up for sale is a .223/5.56 (.223 Wylde Chamber) 11.85" Long Stroke Piston upper from Primary Weapon Systems. Super smooth (push, not a snap) recoil impulse, 3 position adjustable gas block. These are the best suppressor host uppers on the market, IMO. Little to no gas in your face, super clean running and light recoiling.
