About my SBR and her flash suppressor:
It's actually not any longer, its the AAC Blackout with the MITER mount, the MITER mount is for their SPR/M4 suppressor. The majority of the system fits over the barrel, something like 2.5" back, and the Blackout flash hider itself is the only part that is forward of the barrel.
http://advanced-armament.com/product.aspx?pid=630My 16" was originally an M&P15, had Carl Jarl's in Omaha take off the carbine front sight base, then install a low profile gas block and a 12.0 DD Lite rail. The M&P15 lower is actually my registered SBR, so I split the original rifle up. The lower for the 16" is a Palmetto State Armory lower (currently less than $60, completely mil-spec) with a Spike's Tactical enhanced Nickel Boron lower parts kit. Extremely tight rifle, 0 wobble between the upper and lower, and the UBR stock is as solid as I've ever felt. The rifle is heavy, that's no joke, but she shoots well. And the Trijicon TA33G-H 3x ACOG is outstanding, highly recommend it.
