Great video! I recently purchased an inexpensive $85 single shot 12 gauge shotgun from a local pawn shop. Cut it down to 27" overall length with a 19" barrel. I was looking for a sight to add and the options are tough because it's a plain barrel. This sight will be perfect. Ordered it on Amazon today. I like to shoot slugs out of it and I have adapters for it that turns it into a .44 mag, .45 colt, 410 and 17hmr. Now I can shoot these rounds with a bit more accuracy! Thanks!!!
