View Full Version : 5.45x39 AR build mag. questions

04-20-2012, 9:46 AM
Building my first AR upper in 5.45x39.

My question is, can regular 5.56 GI mags. be converted to use this round? I have butt loads of pre-ban mags that I have no problem grinding on or modifying, they're just sitting in storage right now.
How about rebuilding my existing extra mags with new followers if needed?
Does that or any mods change them in a legal sense as far as California is concerned?

any ideas or advice?
