    Purchased this barrel for another SBR upper. Everything looks clean, neat, and straight. I should have bought 2.

    Crane Spec 10.3" Barrel

    Posted by Unknown on May 4th 2020

    I'm very happy with this barrel. Accuracy was excellent with bulk grade 55gr 5.56 and it is very nicely gassed for both suppressed and unsuppressed shooting. Gas-to-face was minimal with a Saker 556k and H2 buffer w/ mil spec BCG. Highly recommend.
