Maybe I missed it somewhere here, but it looks like MK Machining is coming out with some 6BR followers that work in Magpul 7.62 AC mags. For guys running the poly mags these look pretty slick. I've read that some guys do have luck with 6BR in standard 10 rd Magpul AC mags but I've seen conflicting info on that. Either way, I would think these would be an upgrade regardless.
