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.

Very nice complete upper. Paid the extra $$$ for the BCG and charging handle. Super awesome setup. Just attach to your lower and start shooting. Very nice.
