8.5" 556 NATO Parkerized AR15 Pistol Upper Assembly with 7" 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 7.62x51 NATO that maintains the capability of penetrating 0.135" steel at 500 yards.

Specifications:

  • 8.5" 556 NATO Parkerized M4 Contour Barrel with 1x7 Twist and 1/2x28 Threads. Accepts both 223 Remington and 556 NATO ammunition.
  • 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.
  • 7" Narrow Profile Free Float Rail machined from 6061 T6 aluminum. Very comfortable and very light weight. Your choice of M-LOK or KEYMOD attachment points along the entire length at 3, 6, and 9 positions. Hard coat anodized MIL-STD 8625 Type 3 Class 2.
  • 0.750" Low Profile Gas Block.
  • Pistol Length Gas System.
  • A2 Flash Hider with crush washer.

    Review

    The pistol upper is the perfect length. The compact M-LOK hand guard is nice and slim.
    Ruben Belen

    Nice!
