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.
Please Note:
Uppers may present light fouling from our quality control process and/or test firing
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.
***Please allow an additional 2-3 business days of lead time as these uppers are made to order.***
