I finally found a real good Original mint condition Original Bottomland 870. It came with all the paperwork, chokes, and best of all the unused bottomland sling. I plugged in the serial number, it is an October 1992 gun. I believe that’s the first year. It has a 26 inch barrel. I wanted to get the forums thoughts on an aftermarket choke and recommended loads and possible optic add without drilling and tapping. I saw bad reviews about Burris spread bead mount, but I welcome the forums input. Thanks much....
