I have 2new old stockRemington 870/1100 Laser/Lite Mounts made by B-Square.
This was anold design from about 10 years ago. There's a Weaver rail on the bottom of the mount that looks like it's attached to the bracketwith an allen screw, there's a slot that looks like it's designed toaccomodate the included blackhose clamp, an allen wrench and instruction sheet.
I'm guessing that the mount is designed to hang below the barrel and magazine tube.
Only the allen wrenches showa little bit of rust insidethe package.
