    Beautiful right out of the box. No dents no dings. Well packaged. Great look and feel. Quality could not ask for more. Bolted right up to my Anderson lower. No problems what so ever. Love the warranty can’t beat it.

  4. Rated 5 out of 5


    I put about 100 rounds on mine and I love it. Very affordable and lightweight. I just wish it would come w/ a 10″ quad rail.

    This is my favorite hands down of any of my ar’s. This upper on an ati omni hybrid lower has been a joy to carry and shoot! I put an ambi sling plate on it with a single point sling, a surefire light, a magpul afg and a vortex strikefire 2 and she stays loaded with 50gr varmint loads for home defense. I take her out into the hills and she shoots whatever i tell her to! LOL Great upper, great barrel! Upwards of 500rds steel and brass .223 and 5.56 through it and nary a hickup. Was my first of three uppers from CBC. It’s all good!
