Our billet upper is made locally in Phoenix, in our facility. We start off from a solid block of 6061 aluminum and CNC it down to spec. Billet is much harder and more consistent than forged. Forged has a tendency to crack and loosen through wear and tear over time, while billet will last 5x longer than a forged upper. We now include all of our uppers with super durable billet. We Type 3 hard coat anodize our aluminum to make it almost has hard as steel.
Our 5.56 (also shoots .223) 7.5” Pistol nitride barrels are 4150 Chrome Moly Vanadium (ChMV). Chrome, molybdenum, and vanadium are impurities added to the barrels that react positively with the nitriding process with less imperfections and a smoother finish. By not lining our barrels with Chrome, we can keep our smooth bore intact as we do the Nitriding process. The result is a more accurate barrel. Our pistol barrels are more accurate than you would think, shooting very accurately at 100 yards!
This handguard is made with 6061 aluminum extrusion that we CNC to the meet our strict standards with top quality tooling. The top rail is Mil-spec, as are the KeyMod slots. This is a total length of 7” that leaves about half an inch of the barrel (including the threads). We now use steel barrel nuts that can take greater torque specs while not adding too much weight. We pride ourselves on quality and safety, so our 7” handguards allow you to properly grip your rifle (or pistol) while still leaving lots of room to mount an angled grip, flashlight, laser, and a variety of accessories.
Our Barrel nuts are cut from bar stock carpenter 4140 steel and milled out, giving you a better than mil-spec hold for your barrel extension. We torque our barrel nuts 40-80 lbs onto our uppers, giving no chance of loosening while you shoot.
