I just picked up a CMMG 22 conversion kit for my AR15.
I expect to lose some accuracy and range but expect to save big dollars and get quieter.
You’re going to like that conversion kit. Probably not as accurate as a dedicated .22 upper, but perfectly good for minute of tin can.
I had some feeding/jamming trouble with the after market mags that came with the kit (from Brownells). The new CMMG Evolution (I think that’s what they’re calling them) mags work much better.
Lately I’ve been shooting the conversion more than .223.
Have fun.
