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.

Includes:

  • CMMG .22LR bolt carrier group assembly (stainless steel for superior durability)
  • One 25-Round .22LR Magazine (fits in AR mag well)
