View Full Version : AR-15 conversion question

04-07-2011, 7:15 PM
Just received a CMMG .22LR upper today along with a 10 round CMMG .22LR magazine. The magazine is having issues fitting in the mag well correctly. Seems like too tight of a fit. I was wondering if anyone else has experienced this problem before or has the same kit. Thanks

I experienced the same problem. Turns out there are small tabs at the rear of your CMMG mags that need to be sanded down to custom fit them to your lower.

Hope this helps

You have to trim the tabs on both sides to fit.If you can get a hold of blackdog mags,they don't need trimming.
