Installed rail on my Remington 870 Police. The Mesa Tactical Shotgun Receiver Mount Picatinny Rail is a 1-piece component which gives you the ability to mount red dot or optic sight on your shotgun. Also, there ghost ring sights that can be installed to help with your aim and accuracy as a shooter. The model number of this Picatinny rail is MIL-STD 1913 and it is recommended for use with three major shotgun brands: Mossberg, Benelli, and Remington.
You are probably familiar with how Remington 870 shotguns are made with different gauges. The most common gauge in the model 870 is the 12-gauge. This measures the diameter of the barrel. But what you may not realize is the length of the shells is also as critical to consider as their diameter. If you have 3 inches or 2 ¾ inches shells then you need a magnum receiver that can handle it. Of course, the barrel also has to be equipped to handle up to 3-inch long shells. If it is then you can fire them as long as you have a magnum receiver.

Thanks to Andrew and Bill for help and comments. Thanks to S&J Hardware for the rail.
New upgrade package from Brownells. It is very interesting set for Remington 870 owners willing to upgrade their shotguns.
Having fast access to shells is important, especially when using a shotgun because you are limited to the number of rounds you can load. Firing until empty is not ideal so to make combat loading easier you can install a receiver mounted shell carrier or sidesaddle. With a little practice, you can combat reload as you fire a shell without losing your position. Typically, you can choose a four, six or eight shell carrier. Your hands when in the firing position are just inches from the shells.
Typically, an aluminum shell holder will also have a small rail for attaching sights and other accessories. The question many would have is will the shells stay in place. The last thing you want to happen is to have your shells fall out while you are in a tactical situation. Manufactures state the shells are secure even during vigorous movement and recoil will not knock the shells from the carrier.
