With the next version of the “Grunt Series” you still get the same incredible 1 MOA or better accuracy for an unbelievable value, the Veriforce AR-15 Upper Receiver In 5.56 “Grunt Series” Mod-1 is unbeatable. It has a slightly more slim modular handguard than the Mod-0 and the A3 flash hider to top it off. The Mod-1 handguard is a bomb proof beast suitable for the toughest environments that isn’t too heavy and bulky.

Description

Our 5.56 (also shoots .223) 16” 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 barrels should give you at least a 1” grouping at 100yards.  Most of our barrels shoot Sub-MOA, which means under 1” even with ball ammo.  The average for this barrel is 1/2” grouping at 100 yards.  This barrel is good for 15,000 rounds before you will see a drop in accuracy. A 1:8 twist is what we find is the most versatile for the common grain bullets. Lastly, we use Nickel Boron on our barrel extension for the utmost smoothness and durability since this is a high wear and tear piece.  

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.

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.
