CMMG 22LR "Echo" Conversion Kit Question?

[irishdave]

Was wonder if anyone has used a CMMG 22LR "Echo" Conversion Kit for the ar ?
Also can you have a 25 rd 22 mag in a Ar?

I have the CMMG Bravo (bought at CTCS). Runs like a top.

25 rounds is fine when it's a rimfire...

Yup, works great. I use the Black Dog 26 rnd mags. The only issue I ever had was it wouldn’t work with a Gas Buster charging handle.
