Really neat taclight. 180 lumens might not be all that bright, but it's more than sufficient as a taclight. The removable pocket is nice if you want to use it as an edc light and the included mounting ring holds the light securely to any rifle. The tail switch is really neat, with a pressure switch for momentary and a button on the side of the tail cap for constant All in all, this light is super cool and I am very pleased with it.
