I just bought a Mossberg 500 from cabelas and I want to mount a tactical light on it. It will need some kind of picanny rail. I tried searching for al forend with a tri-rail and found out sites like Midway have them but wont fit any post 1988 Mosbergs. I assume mine is post 1988 since i just bought. I am up for suggestions, just need a rail and light? Thanks Howard
