    I ordered a complete upper in 300 Blackout. Shipping was timely, and the price was even better. The upper was Fantastic!! The finish was great, and the fit to my lower couldn’t have been any better.
    The 15″ quad rail really sets it off from other guns. Thank you!!

    I received my upper two days ago. I didn’t end up with the quad rail handguard on my rifle; I ended up with the keymod. The upper looks GREAT!

    I ordered my upper on 26JUN2016. Due to anti-gun issues, Customs had/has CBC Industries parts from Germany on hold. I knew it would take a little time to receive my upper, but I didn’t think two months (no big deal to me).

    After a month and a half I called CBC, they told me why my upper was taking so long. CBC proposed me adding another forward handguad to my upper. I decided to go with the keymod. Roughly a week and half goes by, my order is still unfulfilled. I called again. I talked to Chris. Chris took GREAT care of me! That day my upper was in the mail; CBC sent it via 3 Day Ship USPS. Not to mention, CBC took care of me, when I was being a pain in the butt with shipping address issues (long story).

    CBC didn’t even charge me more for the keymod handguard. Thank You! Hands down the easiest company to deal with and the most friendly! Great people and everyone was very friendly when I called!

    I would order from CBC again. If you’re reading this, you should order from CBC.

    I hope it shoots as well as it looks.

    this is a good upper, I’ve had about 300 rounds through it now and not a single issue.
    time will tell on the barrrel I guess but for now it’s a great shooter.
    the bolt carrier was very tight for the first 100 or so rounds but finally loosened up.
    when I ordered it lead time was 2-3 weeks, it took 4 weeks and 1 day to get to my door.

    Received my upper on 12/12/2016 and was very pleased when I invited it.
    First of all, the packaging was impressive. Upon getting my first glimpse of it I was impressed at the quality, fit and finish of my upper.
    I got my lower from my my safe and attached the two and….voila!! What a great looking gun.
    In a few weeks when I get a BCG and charging handle I’m going to the range to test her out. I’ll post updates when I do.
    Great product that I would buy again in a second.
