CMMG ARC-22 .22 LR Conversion Kits
Shot 700+ rounds out of it so far with 0 problems (except for 2 or 3 "dud bullets" but that was just the ammo). The 22lr shoots the same zero at 50 yards as 223 except it hits about 5 to 6 inches low because of the lower velocity. I've had my ar for a couple years now and spend hundreds, maybe thousands of dollars on improvements and accessories for it and this is by far the best thing ever for an ar 15. Only problem is that I didn't buy this earlier. Could have saved big money on all the piles of .223/5.56 ammo I've shot. Cheap 223 ammo is about $150 for 500, so this kit pretty much pays for itself after your 1st 550 pack of 22lr.

CMMG ARC-22 Conversion Kit
The CMMG ARC-22 conversion kit worked flawlessly with Remington Ammo - I rattled off the first 50 rounds without a glitch.
I switched over to Federal ammo which has received great ratings online - it wouldn't cycle in the conversion kit... not sure if it was just a matter of too little power or what - but it didn't work.
Switched back to Remington and it worked like a champ.
The conversion was extremely easy - one pin.. drop out the main bolt carrier assembly and replace with the conversion... 30 seconds.. and you are in business..
I would like to see the kit offered with some kind of carrying case to protect the unit (and to store your primary 223 bolt assembly when not in use) .. it seems like an inexpensive addition that would add a lot of value.

I recently purchased this item and I will have to say that it works very well. Right out of the package and into my M&P .223 in about 30 seconds. I also elected to go with the 25 round mag (instead of the 10 round) with my purchase and i am so glad that I did because once you get started having fun poping off those .22 rounds it gets addictive and you cant put it down. Two thumbs up for this products ease of use and best of all you get to train (or play) with your normal weapon, Oh and one other thing is that it fits my other two AR's as well.If you are on the fence about wether or not to order this product, jump off the fence and on the computer and get one ASAP and start enjoying your AR!!

I bought this to teach some younger family members how to shoot an AR15. Very easy to install and remove.
Accuracy is great with CCI .22 Tactical ammunition. One of my nephews said "A squirrel wouldn't have a chance against this thing." With a Burris 3-9x scope on a Bushmaster E3 we were getting 9 shot 20 yard groups that I could cover with a thumb. The first shot was typically high and right outside of the group by about 1/2 inch.
FWIW, clean up was minimal. I don't know if that was because the ammunition is clean burning or the conversion unit's chamber insert was very tight.
