Osprey Globals blue laser designed to mount directly onto tactical rifles on any picatinny rail. Mount it under, on the side or on top of quad rail or on 45 degree mounts. Comes with pressure switch or back button. It is harder for enemies to see where a blue laser is originating from compared to a green laser.
Osprey Globals blue rifle laser has the best battery life of all the lasers and reduces follow back, meaning you won't be giving away your position like the green and red lasers. Blue is the easiest to see if you are on the color blind spectrum.
