Right To Bear Complete 4.5" .22LR Dedicated Upper Receiver | 4.5" Mini Barrel | 5.5" Free Float M-LOK Handguard | Dimpled Flash Can | With Bolt Carrier Group and Charging Handle

This mini .22 Rimfire Complete Upper Receiver comes with our 4.5 inch barrel and a 5.5 inch Free-Float MLOK rail, with the dimpled linear flash can compensator extending past the handguard. The bolt is made of all stainless steel construction and we use an anti-jamb dedicated 22 charging handle.

Our complete 22LR upper receivers are fully compatible with CMMG or similar 22 components. Our barrels and bolts are fully interchangeable and follow the same pattern as CMMG.

Every upper is rigorously inspected before and after being test fired, so light fouling may be present.

Compatible with RTB/CMMG .22 magazines, which you can find here

Please note: All semi-auto rimfire firearms operate best with quality copper plated and full powered or high velocity 22lr ammunition.

Although .22lr AR builds do not utilize the functionality of a buffer or buffer spring, we still recommend using both to provide a stopping point/wall that prevents the 22 bolt carrier from moving rearward. Using a buffer and buffer spring will prevent light primer strikes. This is true for all
Ciener/Atchisson 22 pattern platforms.
