Builder's Grade Complete 4.5" .22LR Dedicated Upper Receiver | 4.5" Mini Barrel | 4" Free Float M-LOK Handguard | Flash Can Comp | with Bolt Carrier Group and Charging Handle + 300 Rounds of CCI Ammo
This mini .22 Rimfire Complete Upper Receiver comes with our 4.5-inch barrel and a 4-inch Free-Float MLOK rail, with the linear flash can compensator extending past the handguard. The bolt is made of all stainless steel construction and we use an anti-jam 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.
Compatible with RTB/CMMG .22 magazines, which you can find here
CCI loads this cartridge with a 36 grain copper-plated hollow point projectile. Without forfeiting reliable cycling in a semi-automatic, the lighter bullet achieves a supersonic muzzle velocity out of a rifle-length barrel. The CPHP’s rigid exterior feeds dependably without the need for lubricant, and also reduces overall fouling of the bore.
Features and Specifications:
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.
AMMO RECOMMENDATION: For in-house testing, we utilize CCI .22LR Mini-Mag 36 Grain Copper-Plated Hollow Point Varmint Ammo (1,260 FPS). We highly recommend this ammunition for use with all RTB .22 uppers. It is important to note that the use of underpowered or economy-grade ammunition may lead to less-than-optimal performance outcomes.
