    This is my first Bravo Company purchase and I am very happy with it. This is an upper that I purchased for an AR build I'm doing right now and I'm very happy with it. Also shipping time frame was much faster than expected. I think the only thing I would like to see from you guys as I do expect to purchase much more from you in the future is different shipping options with a free shipping option for a certain dollar amount order.

    M4 upper

    Posted by Chris Wenzel on Apr 9th 2019

    I was wanting to build an ar and did a lot of research and everything pointed me towards BCM, and I couldn’t be happier. Besides a stripped lower and silent captured spring all components are from BCM. Great products, great pricing, and by far the best shipping around. I will continue to buy BCM products as long as I can.

    Simply the best

    Posted by Richard on Apr 9th 2019

    This is being used for my first time build.
    90% of the parts used on this build is BCM.
    All have been first rate.. The upper and lower lock up tighter than my Colt 6920.
    If I had to actually fin something negative. I guess
    it would be, I wish it had BCM's Logo printed on it,
    Like there rifles do..

    These have the tightest bore-barrel extension fit.

    Posted by Stuart Wright on Apr 9th 2019

    If you want to build an accurate rifle you need this upper receiver. The only ones I have ever found other then BCM that are tight fitting were Mega Arms upper receivers.
