16" 556 NATO Parkerized Heavy Barrel AR15 Upper Assembly with 15" Rail and A2 Flash Hider

The 556 NATO (5.56x45) chamber will reliably fire both 556/223 with the highest possible accuracy (223 Remington ammo can be used in 556 NATO barrels). Both rounds maintain supersonic speed beyond 500 yards and equal the accuracy of the benchmark M1 Carbine / M2 30-06 Springfield combination.  The 556 NATO cartridge is designed as a lighter alternative to the 7.62x39 NATO that maintains the capability of penetrating 0.135" steel at 500 yards.

  • 16" 556 NATO 4150 Chrome Moly Heavy Contour Parkerized Barrel with 1x7 Twist and 1/2x28 Threads
  • Mil-Spec Upper Receiver forged from 7075 T6 aluminum with forward assist and dust cover assembly installed. Hard coat anodized MIL-STD 8625 Type 3 Class 2
