The 10/22 is going to be more accurate than the CMMG conversion kit with the standard AR15 barrel and chamber adapter, but the dedicated conversions will give any 10/22, stock or modified, a run for its money if a quality barrel is used. My AR dedicated conversion is almost as accurate as my KIDD 10/22.

 

Thanks. Sounds like it's not worth getting the CMMG kit.
One question for you: What do you mean by an AR dedicated conversion? Are you talking about rifles like the S&W M&P 15 .22 rifle, or something like that? (I don't think you are.)
Or do you mean an actual AR rifle with the barrel switched out to a .22 barrel? If so, what do you use as a bolt in that set-up?
Just curious; probably won't go that route, but I never heard of such a thing.

Thanks

By dedicated I mean an AR with a dedicated rimfire barrel using the CMMG collar instead of a chamber adapter and a .223/5.56 barrel.

The collar at the front of the CMMG bolt/carrier group slides over the stub on the dedicated .22 AR barrel instead of having an adapter that slides into the chamber of a standard AR15 barrel.

 

I think the largest "accuracy" obstacle may not be in the barrel,, it may be in the trigger..

I have been looking at what I should use as a trigger in my AR15,,
pretty much the trigger sellers want you to stay at 3.5 pounds, or more,,

THAT is not a trigger that is conducive to accuracy in rimfire shooting.

I have the 22LR conversion, it came with a beater AR I purchased from an individual,,

I shoot both the 5.56, and the 22LR ammo in that gun with about identical accuracy at 50 yards.

I have installed the conversion about a half dozen times, I REALLY like it when I want to shoot the AR platform, and do not want to listen to the 5.56 making so much racket.

I do shoot at home, maybe at a range, no one would care about noise?

A Triggertech Diamond AR is what you are after. I just installed one in my Mk12 and it's the absolute nicest AR trigger I have ever used. Right at 1.5 lbs as advertised. Not cheap, but they do have 20% off sales a couple of times a year.

 

The CMMG kit as you call it has the dummy bullet that goes into the 5.56 chamber has two issues. First is the LONG bullet jump through the adapter, second a .22lr uses a 1 in 16 twist. Most AR's are 1 in 9 to 1 in 7 twist barrels. The bullet just doesn't have a chance.

A dedicated AR 22 uses the same bolt arrangement as the conversion kit, but has a bullet collar to fit a proper .22 barrel instead of the dummy bullet arangement.

The only reason to get a dedicated AR 22 over a 10/22 is the looks.
