***Disclaimer: 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.
***Please allow an additional 2-3 business days of lead time as these uppers are made to order.***
