Green laser - NcStar Pistol And Rifle Green Laser with Weaver Mount/Pressure Switch

I got this to put on a mosberg shockwave because that shotgun is a little difficult for me to get good sight alignment. This item installed easy and quickly. It works absolutely great. Holds zero so far, 75 rounds fired. The laser is bright, easy to see, even during daytime hours. This is the perfect set up for a home defense shotgun. All you do is put the laser on target and pull the trigger. A definite recommendation from me!
