8.5" 556 NATO Stainless AR15 Pistol Upper Assembly with 10" Rail and Slim Cone Flash Can

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.

  • 8.5" 556 NATO 416R Stainless M4 Contour Barrel with 1x7 Twist and 1/2x28 Threads.

    Ambidextrous charging handle

    I bought three of the ambidextrous charging handles, a pistol upper and rifle upper in 300 blackout. Everything performs as it should and I had excellent service when asking for advice. Great place to do business.
