My ar is transforming. I'm swapping a midlength upper (lower had a carbine buffer tube) out for a RRA 20" predator upper (if it will ever ship). I have the regular carbine buffer and an h2 buffer. I'm trying to find out if the new upper will run on my existing lower/buffer combination.
My google-fu gives me an answer of "it might work fine, you'll have to try and see" can anybody give a firm answer?
