LaserMax's patented design is the only completely internally mounted laser sight system and can be installed by the user in a matter of minutes. The sights come permanently aligned from the factory for center-of-mass accuracy at 20 yards. They will never drift out of alignment. There is no need to re-zero after changing batteries.
