Getting into the AR15 can get expensive pretty fast, especially when getting at least 1 MOA accuracy or better out of your rifle with a modular handguard that accepts Picatinny rails (included). That’s where the Veriforce AR-15 Upper Receiver In 5.56 “Grunt Series” Mod-0 comes into play! The handguard has a 2″ outer diameter and 1.75″ inner diameter. You will not find a better value and quality modular AR 15 upper anywhere, period.

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 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 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.
