    TOP NOTCH

    This BCG is GREAT! Has more of a positive feel to it, than a standard AR BCG. Received in the mail, put a
    small amount of Slip 2000 EWL oil on it, slid into the gun, went to the range.
    Worked flawlessly. Worked so good, I
    ordered another, for a different gun.
    Thanks guys at BCM. You make a great product

    BCG

    I received the BCG in three business days after ordering. It was packaged well along with the other stuff I ordered. The BCG looked and felt good in the gun. The few rounds I put through the gun functioned flawlessly. They also threw in some stickers which I thought was a nice touch. I will be ordering from them again in the future.

    I could not say enough about the folks at BCUSA. I was in need of a bolt carrier for my Colt AR. I came across the BCM bolt carrier, and placing the order at around 11:30 PM Friday, 6/29. Incredibly I was shocked to receive an awesome mil-spec bolt carrier today Monday 7/2 just bfore midday in which I'm extremely happy about receiving so fast. Its another great quality that BravoCompany posses. Outstandinding BCUSA and a big "WHOOA". Will continue to do business with you all. Thanks again.

    Smells of Quality

    As always, shipping was fast. Being a full-auto BCG, it definitely has a little more heft to it. Cutting away the plastic that it comes in, I can actually smell gun powder. You can see where the BCG was sliding and where the bolt picked up a fresh round. Basically, what that means is that this has been fired through a rifle prior to shipping. Let me tell you what - I rather have you guys know that my BCG will work rather than having a brand new one, never tested or fired before and have it fail on me for whatever reason. The quality control BCM has is the best - hands down. You guys have yet to let me down.
