    Ar 15 upper

    Posted by Esteban A on 24th Sep 2021

    This AR 15 upper looks great assembled. Great price for what you get. Hope to see other caliber options here in the future for a AR 10 build as you can't beat the prices here.

    Midlength Monster!

    Ordered this bad boy at I turned around and the UPS dude was like "Happy second Christmas!" That's how fast they ship their products. The handrail is flawless. I threw this on an AERO M4E1 lower with all the 'fixens. I was hitting steel 6" at 300 yrds while trying to miss. The barrel is accurate. I did replace the muzzle break with a VG6 Epsilon. And the Milspec BCG seems to be holding up fine, no cycling issues, no malfunctions. The charging handle is quality. It runs smooth and doesn't show wear like some of the other brands I own. The coating on the handle is made of space shuttle re-entry stuff I swear. Wish I would have purchased like 12 of these.

    Happy Range Day,

    great value in a complete middy FF upper

    Posted by Jeremy L on 18th Jun 2020

    Upper is/was one of the best values in a complete lower around, and based on previous CA purchases, I knew it would be solid. Purchased this last November and built it out with an Anderson stripped lower, Rise Armament 3.5lb trigger, and Fixed MOE carbine stock. Completed the rifle with a VG6 Epsilon brake/comp and a Riton 1-4X. This inexpensive rifle shoots with my other custom rifles and isn't picky about ammo. I wish they had these in stock now I would pick up 4 or 5 more.
