    Solid, light weight

    Perfect upper to finish off a mid-length carbine build. I'm really happy with the weight, balance and bcg is smooth. Can't wait to put more rounds through it.

    I hadn't heard of this company before, so I took a chance. So far, absolutely love the barrel. Will be a frequent shopper.
