Friend has an 870 with factory extended mag. Wants a sling for his gun, and there's a hole at the bottom of the clamp securing the mag to the barrel. I've seen swivels to go in this hole, but now that I am trying to find the maker of the swivel I'm having trouble. Any guidance appreciated.

Thanks so much.
