AR-15 P2 Series 7.5" Upper Receiver BLK 5.56 Pistol Length

Adams Arms P2 Upper Receiver is the tactical, battle-ready, P-Series upper that is drop-in-ready for any AR-15 lower. The P2 gas piston system prevents hot gas and debris from being blown back into the action, resulting in a rifle that runs cooler, cleaner and more reliably than direct gas impingement systems. A short-stroke piston shaft eliminates concussive gas expansion in the upper receiver for less violent cycling, smoother feeding, and reduced felt recoil.

All P2 Upper Receivers come with Adams Arms own free-floating, M-LOK handguard, and when combined with the A4 flat-top upper, there is ample room for mounting optics, lasers, illuminators, or other accessories.

• Ambidextrous charging handle
