    Best bolt/carrier period

    I have seen and used other mil spec BCG but they just don't have the track record like bravo company does. Definitely the favorite part of my rifle and will choose no other company.

    Great BCG.

    I ordered my BCG on Tuesday, New Years Eve, and received it on Saturday. It shipped fast! All is well and I have no complaints whatsoever. I'm replacing my RRA carrier group with the BCM and putting the RRA in a new varmint build I'm putting together. Great product and I can't wait to put a few hundred rounds through it tomorrow!

    BCM top notch

    Just got my BCM bcg couple days ago, night and day difference from stock bcg, 210 uninterrupted rounds through that thing. BCM is the only site that warns you that your package may take a while, yet so far everyone of my packages from them have arrived faster than ever expected. Keep up the good work Bravo!

    Better than the rest

    I've had all kinda different bcg's in different rifles. I have 3 bravo bcg's now and man their perfect. All my other setups run ok but not under stress. My dd uppers and bcm uppers run dry, dirty, cold, hot and even with the cheapest ammo. You get what you pay for and I would trust my life behind one of these. It really is the heart of the rifle and you don't want to run what doesn't work. Period.

    Fantastic BCG

    Fantastic BCG. Clean machining, perfectly staked gas key. I love the fact that they are tested prior to shipping. Also, the item shipped right away--always a plus.

    What else is there to say...

    It's hard to say something the 140 other reviews haven't already said. If you want the BEST BCG for your rifle this is it. The quality of the materials, the craftsmanship & precision of the Bravo BCG is as good as they get. I bought this product so that I would have the piece of mind knowing my BCG would hold up & function when needed...no longer is the BCG the weak point of my rifle!
