Proof Research and SI Defense Video

    Four Guys Guns posted this video on their website. I can’t embed the video so here is the link.

    It is a short video showing the manufacturing of Proof Research Barrels and SI Defense receivers.

    Proof Research makes carbon fiber wrapped barrels. Here is a video we posted last year.
