The CMMG Stainless Steel 22LR Conversion Kit with 1 Magazine.
This CMMG .22LR conversion kit allows the use of inexpensive .22LR caliber rim-fire ammo in your AR15. You can install this in 30 seconds, but just removing the standard bolt/carrier group from your AR and replacing with the the included .22 bolt device.
This unit is blow-back operated and allows semi-automatic firing.
The CMMG .22LR magazines have a bolt hold-open follower. This kit includes a gray-colored 25-round magazine.
Use with AR’s chambered in 5.56/.223 only. Compatible with piston-systems.
Frequently asked questions:
Q: Does this kit work with a .223/5.56 AR-15?
A: Yes! The barrel for a .223/5.56 is very close in size to a .22lr barrel – 3/1000″ larger. This kit allows for shooting of a .22LR from a standard AR-15 upper. A dedicated .22LR upper can also be used, and it will typically increase accuracy somewhat. Most users report that this kit results in 3-4 MOA accuracy (1.5″-2″ groups at 50 yards) with a .223/5.56 upper. Generally, the slower the twist rate on your AR-15 barrel, the better the accuracy with a 22LR round.
Q: Can this kit be used with a dedicated .22LR upper?
A: This kit can be used with a dedicated CMMG .22LR barrel, but you’ll need to purchase this part, and swap out the collar on the bolt – this will convert it to a dedicated .22LR bolt.
- CMMG .22LR bolt carrier group assembly (stainless steel for superior durability)
- One 25-Round .22LR Magazine (fits in AR mag well)

Have Questions About this Product?
I absolutely couldn't ask for better customer service.
Product was a snap to install. shot 100 rounds with no misfires. Ejected all spent casing . great product. The range I went to did not allow steel ammo. Without this kit I would of been out of luck in shooting my AR
Install was incredibly easy and the unit manually cycles with no issue on function check. Looking forward to a range trip in the next few days. Overall great buying experience with AT3. Highly recommend.
Unwrapped the Conversion unit, did a quick operational inspection, oiled it up and put it in a ziplock bag. Went to the range the next day. Shot 60 rnds. of 556, dropped the mag, pulled the 556 bolt, slid in the 22 lr conversion and mag. Shot 200 rnds. of 22lr. No failure to feed, fire or eject. Swapped back to 556 for 40 rnds. / swapped back to 22lr for 25 rnds. rapid fire. Worked great. Shooting 50 yards, accuracy was pretty fair, should improve with better ammo. Overall it was a lot of fun.
Wanted to update my review and move it from 4 stars to 5. Ran 100 hi velocity rounds through the unit and accuracy improved and no malfunctions. Faster bullets seem to give better accuracy. Went from 1 thumbs up to 2.
