View Full Version : 10 rounds of 7.62x39 fit in my 30 round 5.56 mag.

Well I bought a 7.62x39 upper and the 10 round mags were back ordered. So just for fun I loaded some 7.62x39 in my 30 round pre-ban AR mags. 10 rounds fit in perfectly. I cycled some through the action manually and it seemed to feed ok. Now the question is if it will feed when I go to the range. Are there any downsides to this?

People have been using those mags with x39 for a while. They don't feed reliably is the only issue.
