Junk. Does not cycle. Single shot only. Inaccurate, too. Barely holds a ten inch group at 25 yards with the rifle clamped in a rest. Only good thing was that Bass Pro made good on the return and I only lost shipping cost and the difference in tax rates.

Rated 4 out of 5 by peteprentice 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 shot about 100 rounds thru it and only experienced a jam twice. It could have been my dirty rifle, I added some oil and it didnt happen again.
This gives me the oportunity to go out with one rifle,do some plinking then change bolts for some faster hitting shots for the tannerite.

Rated 5 out of 5 by BigWilly555 .22LR AR Coversion ROCKS!
The CMMG .22LR conversion is slicker that snot on a door knob. Changeover takes seconds and the reliability is fantastic. You will give up a little accuracy over the full upper conversion, but when you look at the portability, ease of use, low cost, the value is unmistakeable. I bought this so I could use my AR in the Ruger Rimfire Steel Challenge and I'm very impressed with it so far.
