5.0 Rating What a blast - 1/28/2012CMMG .22LR Conversion Kit for the Ar-15. ARC22 Stainless Steel Kit with 25 Round Magazine.5.0000
Reviewer: Wideglide_07
A must have if you just like shooting your AR for the sheer fun of it! Fired 550 rounds through it right out of the box and had no malfunctions at all using the cheapo Wal-Mart 550 box of Federal .22 LR. Only slight drawback is it leaves the gun pretty dirty as .22s all do. If you like your gun clean, be prepared to do a lot of detailing after a marathon shoot fest. Gotta love this item! Shoots about 3-4 inches low with a 16" mid-length upper and a holographic optic sighted for .223. If you want accuracy, I would suggest a dedicated quick release scope sighted for the .22 only.

I am very pleased with Cheaper Than Dirt’s shipping time, although I personally believe they gouge you on shipping cost. Ordered it Saturday afternoon and it arrived on Wednesday, standard shipping. I read a lot of bad reviews about 22LR conversion kits for the AR, so I did my research before purchasing this conversion kit. I chose the CMMG in stainless steel because the CMMG kit has the best reviews overall, supports its product with customer service, and offers the SS option which makes it easy to clean. I am nothing but happy with my choice. I pulled the bolt out of the package and applied a little oil, then filed the grooves off the magazine. The magazine fits well and ejects as designed. I have only had a chance to quickly fire two full magazines through it…and I mean quickly. The kit worked flawless and I honestly can't believe I waited so long to get one. I am once again in love with my AR now that I can afford to shoot it!!! If anyone is looking at these kits, spend a little more and get this kit and don’t wait a year like I did, you won’t be disappointed.
5.0 Rating Great conversion kit - 7/5/2011CMMG .22LR Conversion Kit for the Ar-15. ARC22 Stainless Steel Kit with 25 Round Magazine.5.0000

I can't believe I waited as long as I did to purchase this kit. So far, I've put several hundred rounds through it with very few malfunctions. Great plinking conversion. I did pick up the Black Dog magazine to use with it based on reviews, and it seems to work fine. If you have an AR15, this is almost required equipment.

First of all, I got the stainless one. I don't know if that is typical but I expected the regular one so that was great. Installation (if you can call it that) is simple. Magazine needs to be "fitted" for your rifle. There are 2 notches on the back of the magazine that can be filed down if needed. This is a feature not a bug. DO NOT USE Remington Golden Bullets with this kit! It even states that in the instructions. Thats all I had at the time and they will jam jam jam jam. I bought some Winchester "WalMart" .22s and no jams with over 300 shots fired. I like it. When you "sight it in" you have to remember that the point of impact will change from .22 to .223. I hit dead center at 25 yds with .22s and .223's land about 1-2" high. If you want the most accurate .22 kit just get a dedicated upper. For a cheaper way to enjoy your AR just get this. Its worth the money.

Reviewer: Adam
The fit and finish of this unit is very good. The stainless contact points need VERY little oil to run perfectly. I was concerned about accuracy with a conversion kit, but this unit shot 3" from a supported position at 75 yards easy (eotech no magnification) I ran all CCI ammo through it for about 1000 rounds the first time out. Had ONE stovepipe which is not too shabby. Would highly recommend the Black Dog 50 rd drum to go along with this. More firepower and easier to load than the mag in the kit, although that mag functioned just fine as well. My rifle is a 14.5" BCM upper, 1:7, midlength gas, RRA trigger kit (rounded hammer). You will need to clean house after each range trip, but it's an AR so that's easy to do well.
