10.5" 556 NATO Parkerized M4 Barrel AR15 Upper Assembly with 12" 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.

Specifitions:

  • 10.5" 556 NATO 4150 Chrome Moly M4 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

    Chrome upper

    Have not received was expecting it a week ago said delivery was running late still have not got it.. not happy with USPS but I am an adult and a rational human being so I know in my heart that the blame is on USPS not AR15part.com. Ar15part.com shipped my order in less than 24 hours!! Ordered after they closed on the 10th and they shipped it on the 11th. 5 star service.
