This person had radical firearms AR 15 I think, and it worked fine in it. So far in my experience very few ar15 will not work with a pmag gen 3, but rufjed from other countries might have more issues if their magwell is pure stanag. In that case I use lancers or duramags
Good to know. I haven't had any issues w/ my lancers or gen 2 window-pmags but I just ordered some gen m3s from opticsplanet. Hopefully they work.
