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)

Cheapest price I've found online. Shipping is extremely fast. I would definitely do business here again.
Works great, slides right in after you take out your .223/5.56 BCG and you can fire away. I heard getting a .22LR barrel will improve accuracy drastically, I might do that.
I absolutely love it. It works flawlessly. I've been watching for this to go on sale for months. Great price! Great little product.
Great product and best price around thru AT3 Tractical, did a lot of shopping before purchasing.
I have a S&W AR MP15 Sport have ran around 400 plus rounds between Federal and Winchester ammo thru it so far with no issues.
Delivery was fast within 2 days from AT3 will differently check their website for future needs.
I'll definately buy from at3 again, my order shipped the same day and arrived two days later, not to mention great prices. They also replied very fast to my question. Keep it up!
