    Awesome BCG!

    Posted by Ross Earles on December 29, 2023

    This BCG is great! This is a balance of form, function, and aesthetics! Paring this with a dual ejector C158 bolt and you are going to be hard pressed to find a better carrier combo for the price , folks! I would like to see these offered in a chrome lined option! These are going to be running in all our builds moving forward! Great job KAK! Love this!
