The 223 Wylde chamber was developed to reliably fire both rounds with the highest possible accuracy (556 NATO ammo can safely be used in 223 Wylde barrels). The 223 Wylde chamber was desiged to have tighter tolerences and be slighty more accurate than the 556 NATO chamber. Both rounds maintain supersonic speed beyond 500 yards and maintains the capability of penetrating 0.135" steel at 500 yards.

  • 15" 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.

    Great looking upper

    I love the way this upper turned out. The only reason I gave it a 4/5 not a 5 is cause the upper receiver and the rail are a different black. The rail is a classic mill spec black while the receiver is a more glossy black. It’s not a deal breaker as it isn’t that noticeable when the entire gun is assembled, but as a perfectionist it is a little frustrating. But other then that a absolute 5/5. I especially love the spiral flute barrel.

    First time using AR15parts. So far so good......quality appears to be stellar. Will no more when build is completed and rounds down range. Fast ship and great communication.

    Great assembly

    Got this for one of my friends who just got into AR 15's. The day it came in he went out and shot it. 25 mph cross winds and he was still hitting a 24" gong at 600 yards. Definitely sub moa barrel. I'm going to get one as well, but with different handrail and muzzle device. Going to turn this into my 3 gun rifle.

    Best money I ever spent!

    Ordered this upper to complete my varmint gun and all I can say is wow! Super accurate right out of the gate. I am easily punching 1" groups at 100 yards and that's with a crappy trigger. The keymod rail is nothing short of perfection in design and function. I wasn't sure about the FDE color at first but it was a perfect match to my magpul furniture. Plus it turned out to be about $150 cheaper than I could find anywhere else for this quality and this particular configuration. I will definitely be back for more!
