This is the one you need! - Streamlight Tactical Flashlight Mag Tube Rail Mount

Had to see for myself so l made the purchase. have a Remington 870 Tactical and l've read where people have had to modify in some form or another either the light or the holder. So since this holder is made for their light l had to see for myself so l made the purchase. I'm no gunsmith or have any experience with gun modifications and was able to do this myself! So lay out some time, take your time, make markings with painters tape (since l'm a perfectionist and want things back like they were), and in an hour or less, you'll be attaching your light!!
Pros: Will fit Remington 870 Tactical
Cons: Haven't found one
