Paul,
Got my 12.5" BCM upper on Friday. I didn’t have time to ‘shave’ the FSB so I installed a Troy low-pro for the meantime. I did dimple the barrel at the front screw of the GB and I’ll likely just pin this GB next week. I installed a 11" Troy/VTAC tube and a DD rail mounted front sight with a Surefire X300 in front of it, BCM black Troy rear sight and my Aimpoint C3 in a LaRue LT150 mount. I installed my KAC Triple Tap comp.
I installed the upper on one of my SBR lower yesterday and sighted it in at the NRA Range last night. Ran 150 rounds through it with an H2 buffer. Shot 75 rounds of American Eagle 55gr FMJ, 25 rounds of PMC 55gr, 25 rounds of Mk262 Mod 1 (77gr) and 25 rounds of Prvi 75gr BTHP Match. It ran 100% using a 1 Lancer 20 round mag and 1 Tangodown 30 round mag. It shoots very soft and smooth.
Thanks Again,
Robb
