    Buffer Tube

    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.

    BCM® Milspec Carbine Receiver Extension (Buffer Tube) 6 Position -

    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.
