The CMMG .22LR AR Conversion Kit w/3 25rd Magazines is perfect for affordable training and practice with your favorite AR-15. This drop-in kit lets you shoot inexpensive .22 LR ammo through your standard AR, maintaining the same weight, balance, and feel — only the slide won’t lock back after the last shot.
Installation is quick and requires no tools or permanent modifications — simply replace your existing bolt carrier group. The stainless steel construction makes cleaning easy and ensures excellent corrosion resistance. Designed for semi-auto AR-15s only (will not work with M-16s), this kit includes three 25-round magazines, making it ideal for extended range sessions.
Notes:
- Rimfire conversion kits are NOT compatible with gas piston equipped AR-15's. The piston will not allow conversion to fit in the receiver.
- Light and subsonic ammunition will not operate as reliably (if at all), compared to standard or high velocity ammunition
