    The CMMG Stainless Steel 22LR Conversion Kit with 1 ten round Magazine.

    This kit is great for states that place a limit on magazine capacity.

    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. This kit includes a ten-round gray 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 10-Round .22LR Magazine (fits in AR mag well)

    Great product, best customer service!

    I had been considering a drop in .22LR conversion kit for a while. When AT3 posted a spectacular deal on Reddit, I couldn't pass it up. I was in such a hurry to buy one before they sold out that I forgot to even include the coupon code for an additional $10 off.

    My order shipped in a day, and arrived in two more. A quick email to customer service and they even refunded me the $10 from the coupon code I forgot to enter!

    Hands down some of the best customer service, easiest ordering, and fastest delivery.

    The kit itself works flawlessly. I have a 16" barrel with a 1/7 twist, but I've had no trouble cycling 40gr CCI Mini-Mag and Standard Velocity rounds. The loss in accuracy is no big deal for simple paper punching and plinking, which is so much cheaper with .22LR, and I think I'm already close to paying off the kit in ammo savings after a couple range trips.

    Thanks AT3, I look forward to doing more business with you in the future!

    We are happy to hear you are pleased with the customer service and that your order is working out well for you.

    Might be fine in an AR pistol

    At3 shipped it right out. Surprised me how quickly I received it. This unit works. But if your looking to hit anything you would be better off throwing rocks. Placed it in a .5 moa rifle to find I now had a 12 + moa rifle. This was with CCI Mini Mags. Also had to adjust sites up 12+ inches to be on paper @ 50 yards. Not worth the space it takes up in my range bag.

    Excellent addition

    Simple installation and take up very little room when not in use, while basically giving you another gun in your arsenal. The biggest surprise is it accuracy. The shells you use does make a big difference in accuracy. I used 36 gr Remington bulk and 40 gr. Federal, CCI and Winchester. The CCI mini mag. did excellent with a 50 yard five shoot 3/4 inch grouping. I did have a few jams but I contribute most of that to the shells being used. The jams were easy to remove which I can't say the same for my Remington 552. I use it in my CMMG 18 inch SS rifle but will also try it in my Windham 5.56 next time. Overall I was impressed with the addition and would order it again. Can't say enough good things about at3tactical.com. They followed up with me even though I had no problems. This is my third order from them and they have exceeded my expectations in shipping and quality of products.
