Light rail - Streamlight Tactical Flashlight Mag Tube Rail Mount

i wanted something cheap and durable to attach a streamlight tlr1 or insight m3 or m3x to a mossberg 500. this did the trick. the only thing is that streamlight said it might not fit a remington 870. i will be buying an 870 in the future and if this mount fits on it, i will be buying another
Pros: cheap, light, fits any light
Cons: not sure if it will fit an 870
