Yeah, JAC is an ***hole to say the least.My Ceiner kit is very good. I did have a magazine that gave me issues, and a call to JAC was less than friendly, so I discarded that mag and replaced it with Black Dogs from Brownells. It's flawless as long as it's kept reasonably clean.

I also have the CMMG conversion, Brownells only offered 1 mag back when I ordered it and now there shipping with 3
Whats your guys experiences with these? I have a friend with a ceiner one, factory mag, and 4 bulldog 30 rounders for $200. I'm wanting a supressor platform, and seems like this would make a great practice rifle.
