I am unsure how many mags I have. Most of mine are still new in wrapper, sitting in the corner of my gun room. I continously buy ar47 mags whenever they are available, since those are my primary 3 rifles. I have never kept track of the ak mags. Hopefully one day soon I can make time and go...
I have enjoyed my New Frontier Armory ar9 lower. Zero issues and it didn't care which upper I put on it. Glock mags ftw. I do plan on SBRing this year.
A couple ar platforms in 7.62x39, one ak, m&p pistols, shotgun, a newly aquired savage .308 and a fvsr. I don't even have an ar in a traditional caliber, how funny is that. I can thank @NWS for that
