For easy installation and adjustment of front rifle sights. In the past there was only one accepted way to install a front sight in a ramp - pound it with a hammer from the side. This marred a beautiful finish and loosened or damaged the ramp. The Front Sight Pusher provides the best way to install a front sight in a ramp. By equalizing the pressure on a ramp and sight, it permits installation without marring and eliminates excessive pressure on the ramp. Sight is smoothly and accurately moved into exact position. Works with any 3/8" dovetail ramp. Not for use with dovetails cut through barrels. Will not work on handgun slides.
