    extremely well made. Decent wall thickness and o.d. is the same all the way down. Perfect fit with mil-spec stocks.

    It's a Mil-Spec buffer tube just like everyone elses right? Measurement wise that is a correct statement, but quality wise BCM is on a different level than most companies. The finish and fit on this tube is better than most other manufacturers.

    A quality produvt that fit perfectly onto an old bushmaster receiver amd mated up with a bravo company buttstock . Together these two components made my rifle much more comfortable to shoot and handles better than the old buttstock.

    Products are great but I’m not ordering from any company who ignores my request to ship UPS or FedEx. USPS service is unacceptable and I refuse to use it. All kinds of companies to order quality products from.
