I know I'm new here but I actually looked into buying an ar complete assembled upper a little over a year ago and gse is not bad but from what I read and asked around Spikes(also out of Florida), noveske, POF, and bravo company(BCM) are better(the best from what I read), went with BCM(it was the most cost effective for what I wanted) myself and haven't had a jam once(gf, not to jinx it) sorry can't give you a round count but well over 750 between me, best friend and Brothers use. check out ar15.com on the top you'll see a lot of vendors I didn't even know existed then you have to read up. good luck buddy
ps. anything under 10in is a flamethrower, saw a sig 556 pistol and now I'll be looking for one as well!
