22RB Dedicated 22 Upper-9.25″



Nordic Components’ 22RB dedicated 22 upper receiver converts your standard AR-pattern lower to a dedicated .22LR for recreational shooting, training, and hunting. 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.

9.25 Pistol/SBR upper-all NFA rules apply


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.
