Im sure someone has thought of this. But in my searches, I have found no info on the subject. We all know Armalite uses modified M1A mags. Reason being the AWB.I know it was not kosher back then to make a new firearm to take an old magazine. But now is different, I want to modify my Armalite lower to take unmodified M1A mags. I know it sounds like a good idea to me, but Im no gunsmith or machinist. I am looking for ideas, because I have some friends with access to a CNC machine. If I could get some specs, ideas, whatever, I just might go forth to the next step and buy some extra lowers to see what works. Has anyone else had any brainstorming on this concept?
