CMMG AR15 .22 Conversion Kit

I think someone mentioned accuracy in the previous responses. Reliability is acceptable. Accuracy however is not. 22 LR likes a 1 and 16 twist. Most AR-15s are half that or more. Bullet has difficulty stabilizing. Great for SHTF though.

I know this is the general thought, plus the bullet has to coast up to the lands, and the barrel diameter is a little off...

With that stated, I shoot about 2 1/2 - 3 MOA with mine 'slung up'. That's about what I get out of non match 5.56 as well.

Just get a designated 22 upper. They aren't that much more expensive and are deigned for 22lr.
