Review on Feyachi Red/Green Laser Sight Low-Profile Compact Picatinny Rail Laser For Pistol Handgun Shotgun Rifle by Alexander Roberson

easy to install but the adjustments are not ideal. This was my fault for not ready more clearly how the adjustment of the laser works. There are 4 small screws in the front of the laser that you have to turn to adjust left, right, up and down. Each one makes its own adjustment. Once I figured out which did which directional alignment, it was easy to sight in using a chambered bore sight. Brightness for a green laser could be better. At night or low light, it works great. but in daylight, it is faint. Overall, for the price, it works.
