I am looking to build a pistol caliber AR. I already have my 80% frame laying around and have a pistol caliber upper receiver coming. It can be used for 9mm and 45.
I really want to do one in 45ACP, however, I am uneducated on the mag inserts that go into the regular 556 frame.
I see that the 9mm ones are available for G17 mags, of which I have some already for my p80. But is there anything for a 45acp ar that takes 1911 Mags for example? Well or maybe greasegun mags?
I dont really want to start buying more different mags if I could avoid it and think it would be nice to have better compatability between the handgun and the PDW for mag interchangability.
Maybe someone can help out and explain, I really lean toward the 45 since I am also able to reload more for it than for 9mm.
Another question is, what do I need to look for as far as buffer and spring? I read that they are different for the blowbacks too?
