Ok for a range rifle or safe queen, maybe. - SightMark SM25016 LoPro Mini Laser Sight Green Laser Picatinny

Bottom line with rifle mounted laser devices: you get what you pay for. Does it work? Yes. Will it withstand the abuse of being mounted to a actual weapon and dragged through harsh environments? Not a chance. I stripped out the screw type mount because it kept loosening and falling off. Pressure switch is not great either. But the green laser works well.
