Rail mount flashlights are tactical weapon lights that are attached to a firearm using a rail. The rail mounts are located at different positions on the firearm depending on the weapon and the rail system design. There are six rail systems most commonly used for firearms and they are the
Dovetail rail, Weaver rail, Warsaw Pact rail, Picatinny rail, KeyMod and M-LOK. Make sure to identify which rail system your weapon requires and determine the length of the weapon rail. The weapon's rail must exceed the minimum length of your rail mount flashlight or the weapon light will not be compatible with your specific firearm.
