Taking the .300 BLK Plunge (New Upper)

After threatening to for the better part of a year, I'm finally taking the plunge on building one of my spare lowers into an AR pistol. The catalyst for this was stumbling upon this BCM 12.5" .300 BLK upper w/ SiCo mizzle device and Aimpoint Comp M4 for what I considered a fair deal:

I have two lowers to choose from, the brands of which escape me, as well as a RRA NM trigger, standard A2 pistol grip and Geissele LPK standing by to get pieced together. All I need to decide on is which brace. 

I will probably use the Comp M4 at first, but intend to sell it and use this upper with a VX-II 2-7 I have laying around for short range, suppressed hunting. I'll also be using this upper almost exclusively suppressed with my SiCo Omega 300 can.
