Query: Not half bad...

Alright then.Pros:-Strong Laser Dot-Comes with Batteries-Cheap-Arrives at a timely manner-Meant for Piccatinny railsCons:-No instructions on how to adjust laser-Laser dot is usually off center and needs electrical tape around the laser housing so that the clasps will hold it in placeAll in all not a bad addition for my project salvo, but needs some "customization" for maximum accuracy. I got it instead of a laser dot sight because you cant exactly rest your head with a mask on against the gun to aim.
