That which one of my favorite YouTubers says is his “most valuable” firearm is one of my favorite (carbines?) also, and his has one of my favorite creations on it. OK, he doesn’t mention his M1-B optic mount, and doesn’t have an optic on it for the video, but we’ll take what we get.
He had his AK worked over at Rifle Dynamics, which is one of our distributors. They seem to know what they’re doing, and that is something worthwhile.
