When Assembled, this will be 20.5″ Long!
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.
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 M-LOK slots. This is a total length of 4” that leaves about half an inch of barrel (including the threads). We now use steel barrel nuts that can take greater torque specs while not adding too much weight.
Our 5.56 (also shoots .223) 5.5” 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 than you might think.
