Patent attributes
A laser pointer on a seat of a firearm as an auxiliary sight is disclosed. The pointer comprises a cylindrical housing comprising a forward aperture; a light emitting mechanism in the housing, the mechanism being adapted to emit laser beam through the aperture to impinge on a target; and an adjustment ring rotatably put on the housing, the adjustment ring comprising an outer knurled ring, and an inner cam ring comprising an outer projection secured to the knurled ring, an eccentric bore for receiving a rear portion of the mechanism, and a rear narrow shoulder as a stop. A firearm user can rotate the adjustment ring to adjust the laser beam direction and thus the light spot on the target. The corrected adjustment ring can be fastened. Hence, the invention can aid the eyes to quickly line up the firearm on the target.
