I've been a member for a while and do a good bit of lurking. I like long range shooting but I'm not a fanatic. I do my own reloading and gunsmithing for rifles and pistols and have for a whole lot of years. Recently I decided to try an *80**%* build for an AR 45. Waiting on "Joebob" to send me my last piece. Anyone here done a 45 AR build? I'm sure that I will have a question or 3. One that comes to mind is about mags. Which ones will actually work. I understand that I need large frame mags, but since I don't have a Glock 45 I'm not up on which mags will and will not work well.
