    Blemished/demo receivers

    There is absolutely no way I could be happier with this product. I ordered 2 receivers, with the expectation that they would have some type of flaw or imperfection. I was pleasantly disappointed to find that both were completely flawless in their condition. Shipping time was amazingly fast and efficient as well. If this is how BCM rates their damaged products, I have the highest of expectations for their front line products. Excellent job guys.

    “Blemished” M4 upper receiver

    Couldn’t find a blemish on the 4 I bought. The BCG bore lines up perfectly with the barrel extension opening, and required a very light touch with the lapping tool for a perfect fit. I love these receivers.
