Only 10 Remington 870/1100 rails left.....$169.95. This is a limited run on the Magpul FDE cerakote rail. Once these are gone I'm not sure if and when they will be back.
These will not work if you have anything sticking up higher then a barrel rib. As you can see from the photo normal front sights are not an issue but if you do have rear sights they would have to come off.
