    Outstanding product

    This was a last minute purchase for a mk12 clone build. I am extremely pleased with this bolt. It came well packaged with a protectant lubricant on it. I was very surprised to get it in the mail just 2 days after placing the order. Great job guys. I will be ordering from y'all in the future after I go to Korea.

    BCM Bolt Carrier Group (MPI) - Auto

    Haven't used the BCG yet but the service and delivery speed was fine. It's amazing that Bravo can't
    keep stuff in stock. Just shows everyone likes BCM.

    Disappointed

    I just received my bcg from you all and was very excited, however, I opened the package
    And upon inspection it was scuffed up at several points. I understand that you all test it and all, however this first one is more wear than one of my lower quality bolts has that has been shot many times. Really disappointed I've been told and read you all have excellent quality I expected better.

    Well made

    All what I have to say is if it's not perfect I wouldn't buy it again (This the 2nd one for different AR). Shipping was late for 2 days more than the expected delivery date but it's not a big deal, it's worth waiting for.

    New build bcg

    I ordered a bcg from Bravo Company not because it was the cheapest, not because it had the latest coatings, but because of it's great quality and mpi. Item was shipped quickly. Can't wait to try it out.

    I feel sorry for the peeps that go cheap on other bcg;s, but that's their problem. Simply in my book the Best value on the market. My shooting buddy's are drooling. Can't beet the shipping, 2nd to none. thanks BCM.

    Great service and great product!

    Shipping was immediate and the product arrived a day early! Always appreciated!

    Fit and finish of the BCG look excellent, except for a small scratch down to the steel at the back of the carrier.

    With a grain of salt

    I can't really comment much since I haven't finished building my rifle. The finish and look of my bcg is just fine. I can comment on the service which is excellent. My items beat my other items I order on amazon to the house, I'm a prime member. Website was easy to navigate with useful information, and minimal "tactical talk". This is my first rifle I'm building bravo parts but so far I'm pleased. Don't know enough yet to recommend them.
