Great Lakes Firearms AR-15 300 BLK 7.5" 30rd Tungsten Pistol

A 7.5 inch 300 BLK barrel is the shortest practical configuration for the cartridge, and it is close to what 300 BLK was actually designed around. The powder burns almost completely in that length, so you give up far less velocity than a 5.56 pistol does over the same distance. Great Lakes Firearms builds this one on a billet aluminum lower with a matching upper, both coated in Tungsten Cerakote, and hangs a short M-LOK rail over the barrel for a light or a hand stop.

A GForce Arms Ace of Brace adjustable brace is fitted at the rear. The barrel is nitride treated inside and out for corrosion resistance and easy cleaning, and the controls are standard AR-15, so triggers, grips and charging handles from the parts bin all fit. One 30 round magazine comes in the box. Suppressed with subsonic ammunition this is about as quiet as a centerfire firearm gets, and unsuppressed it is a compact truck gun that gives up very little to a 16 inch rifle inside 100 yards. The tungsten finish is a light gray that separates it from the wall of black AR pistols without going loud about it.
