10.5" 556 NATO Stainless Steel M4 AR15 Pistol Upper Assembly with 10" 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:

  • 10.5" 556 NATO 416R Stainless Steel M4 Contour 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.
  • 10" 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.

  • Pistol Length Gas System.
  • Mil-Spec A2 Flash Hider with crush washer.

    I sold my pistol upper to buy a more aggressive upper. Snug fit. No shake. Looks great. Cant wait to hit the range.

    Great!

    I bought this upper to use for work. Attached it to a Colt M16 lower. I put the light, red dot, backup sights, and a suppressor on it. There are no negative issues. It has functioned flawlessly. Accuracy is good. I only go out to 100 yrds with the open sights. It is nice to clear rooms and buildings with less weight and less length on the barrel. For this short guy, my muzzle no longer drags on the ground. The shipping was time and packaging was good.
