One of the most common upgrades you can make to your Remington 870 shotgun is adding a flashlight to it.
A flashlight mounted onto your Remington 870 will give you the necessary light source you need to see what’s nearby. If you use your Remington 870 for home defense then the flashlight mount will come in handy during day or night. Even if there’s daylight outside, there could be a target that comes indoors or in an area where it is shaded from the sun. It is better to be safe than sorry so it is always a good idea to equip your shotgun with a flashlight mount. It is lightweight and doesn’t take up much space on your weapon.
