My mind wanders when I am bored at work, and this is one of those times. I think it would be interesting to build an AR pistol in .45 super with a 10" barrel. I have experience building AR's, but do not know anything about the .45 versions. First, what options do I have for lowers for a .45 AR? I would want it to run off of Glock mags. I am also thinking that a blowback upper would be my best option. Any ideas on what buffer weight I might need to run a .45 Super upper? I do realize that this is an odd duck, but there is actually method to my madness.
