CMMG drop in .22 conversion kit with CMMG full body magazine. This model is semi automatic only. Additional magazines will be available in the near future. All CMMG .22 LR magazines have a bolt hold open follower. When using the bolt hold open follower, magazine will only hold 26 rounds. For best performance use a rounded style hammer, notched hammers can cause function issues. 36 grain bullets have proven to be the best choice for function. The PRI Gas Buster charging handle will not work with our .22 Conversion kit
Also available in AWB state 10 round version
The ARC magazine may require some fitting to your receiver. In order to provide you with a custom fit in your lower receiver, the back of the magazine features two small bosses. You may need to file, sand, or shave the two bosses down until the magazine will fully and freely enter your receiver.
