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)

Hopefully yours will fit.

I ordered 2 of these and one was 7/8” wide and it fit perfectly. The other one was 1” wide and it would not fit. They were in the same exact packaging. I contacted AT3 after we tried them both out and the rep said he would contact CMMG the maker. I waited a week and then contacted AT3 again, this time I had to leave a message and I still have no answers. Would at least like one that will fit or a refund.

So sorry to hear about the issue, Elizabeth. We sent you an email to resolve the issue.

Couldn’t be happier

I finally got out to the range with my new conversion kit….I was able to shoot through a 500 round box of .22 LR and I experienced 0 issues or malfunctions.

I literally could not be happier. This thing is exactly what I hoped it would be. Shooting .22 is currently like 1/15 the cost of shooting .223….So this conversion kit will allow me to get a ton more time on my AR’s. And quite frankly, will pay for itself in short time when the ammo savings are factored in.

I was a little surprised at how dirty my AR for. Especially the lead fouling in the barrel. But that’s not the conversion kits fault, it’s just what you get with .22. And I’ll try some different ammo to try and help with that issue. Overall, I’d recommend this to anyone considering it. But get extra mags, you’ll want and need them!

Thanks for sharing your feedback! We're glad you're satisfied with your purchase. Cheers!

Great product.

Second one I purchased. First one worked straight out of the package. My 79 year old Dad really enjoyed shooting his M4 again. Built a 223 Wylde upper just to shoot the conversion. Gave it to my son in law to let the grand kids shoot. Now I'm building the second one. Looking forward to Pop and I shooting again.

Thanks for sharing your feedback! We're glad you're satisfied with your purchase. Cheers!

Not hype

Arrived faster than I anticipated, shaped it right in and started firing roads, already over 300 and flawless action. There's a reason there selling out everywhere.

Thanks for sharing your feedback! We're glad you're satisfied with your purchase. Cheers!
