Do what their supposed to do. I can’t tell any difference between the CMMG or Duramag. They look identical and seem to function the same. I’m happy with both but the Duramag is slightly cheaper so I’d go with them the next time.

worked great I had no problems at all;

Better than fair prices and outstanding delivery time.

I got exactly what I ordered, very easy transaction and super fast shipping. Thank you.

Mags work great
