    Worth every penny!

    Just got done with my first AR build. After much research I decided on this BCM bolt carrier group, and I must say I am very pleased with this bcg. I have run hundreds of rounds without a single problem, which was to be expected with BCM's quality...When I was narrowing down the bcg's in my search it was between this BCM, a Spikes Tacitcal, or a Daniel Defense. All of them being auto bcg's and all having great reviews, it came down to price and the fact that the BCM was in stock. Buy one and you will be more than happy with this bcg!

    Great bcg

    If you are building your own, this is the bcg to get. Quality is amazing and only a few bucks more than the cheapo DPMS one. Super fast shipping too, ordered this Friday morning and received it on Monday (unlike many competitors who don't mind making you wait a week or more). Bravo Company USA definitely puts the customer first with their quality, good pricing and quick order fulfillment. Thanks!

    High Quality

    Easily the highest quality BCG I have seen, over CMT, LMT, PSA and M&P. The staking is different but better IMO more material pushed into the screws. Nice finish.

    Fast shipping!

    Ordered this BCG late Friday and received it early Monday morning, caught my off guard cause I didn't expect it till the following Wednesday.

    Very impressed with this product. Extremely solid piece and works like a tank.

    high quality

    I bought this as a back up to dpms bcg, Wow I was impress of the quality. The extractor was bigger and overall so mush better made. The logo on it was is pretty cool too. I was so impressed I bought a BCM Standard 16" Mid Length Upper Receiver Group w/ Troy Standard TRX 11" Handguard to match! This web site is going to make me go broke LOL !

    Nice

    Just got this in the mail after a 2 day wait. As usual great shipping. Has a couple small cosmetic scratches from the test firing mentioned in the description but that would happen from being in my rifle anyways. Also the bolt face had very heavy powder residue on it but no big deal after a little bit of cleaning. Very satisfied with BCM again. I just wish they wouldn't use USPS due to the fact that I received 2 BCM packages today and one had a large hole in the side and the other appeared to have been stepped on several times and the box arrived destroyed on my door step.

    The best BCG I own

    The bcg is great and for the money it is unbeatable. Very tight tolerances and the markings are great. Came dirty from being tested as expected. Ordered another one!
