CMMG/Brownells caliber conversion for AR15
This is a CMMG (Brownells branded, cat # 080-000-558) caliber conversion kit.

Probably shot about 200 rounds with this. I just bought a dedicated 22 upper so really do not have a need for this any longer. Comes with one 27 round magazine. No issues, worked great.

$120.00 shipped

I have the same thing from CMMG except the Stainless steel version. I've put probably 2500 rounds through it with only minor issues. Those issues were due to dented rounds, nothing directly related to the conversion itself. I've found it to be fairly accurate.
