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 firingAlthough .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. SKU: BG1622LR12SL-BLK UPC:
