These changes, potentially differing cosmetically from shown images, ensure enhanced quality and performance. This may include ambidextrous sling loop endplates or an upgraded extra power spring.*This product is manufactured based on parts on hand. It may feature a standard or oversized trigger guard, depending on what we have available at the time. Also, it may have a standard curved trigger or a flat trigger.* Please Note:Uppers may present light fouling from our quality control process and/or test firing 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. SKU: BG1622LR15SL-BLK-IBOR-FULL-LPK-TS UPC:
