Gents I want to chime in on this conversation with some interesting information. C Products Defense and the improved 30 round 7.62x39 magazine WORK FLAWLESSLY out of the box. I had 20 ASC mags that I could not get to work no matter how I modified them. I also was dealing with failure to fire which is a common problem with the surplus 7.62x39 steel cased rounds (Tula, WOLF, etc). I found a guy on the internet named Russ Cason who owns Liberty Gun Works, Inc. in Bradenton, FL. I was about to give up on my AR-47 build until he saved me from myself. He builds his own 7.62x39 AR-15 platform rifles and from what I have witnessed, they perform as you would expect any rifle to perform. He told me he had been working the magazine issues with the C Prod magazines for a few months. He contacted C Products Defense in Bradenton, FL to get their assistance in addressing the problems. He pointed out the reasons for the binding in the magazine and the feed lips that someone posted on this thread already. He helped them build some prototypes with those modifications and tested them thoroughly on his own weapons. Needless to say, I am very thankful for his contributions to the community to finally get a product worth buying.
