AR-15 22RB Pistol Upper Receiver Assembly 22 Long Rifle

. The 22RB is manufactured using the same materials as most standard AR15 rifles, ensuring that it is a dedicated .22 upper that looks and feels like a centerfire rifle.

The 22RB’s match-grade barrel also comes prepared to accept a suppressor — the barrel threads are cut to the proper spec for most popular .22 suppressors, and a mortise to accommodate the O-rings found on certain suppressor models is machined behind the threads.
