Noted! What I'm building won't be completely top shelf but certainly not bottom either. I want it to run as reliably as any other firearm I haveThat's a nice build list.
The lower is dedicated 9mm which is mega easier on the eyes than a converted 5.56 magwell.
(as you know)
My QC10 came with a "tune-able" buffer (multiple weight combos possible) and a Sprinco "Red" buffer spring.
They are adamant about using that spring for AR9.
