In the past, there was only one acceptable way to install a front sight in a ramp - pound it in with a hammer from the side. This method frequently marred a beautiful finish and loosened or damaged the ramp. The Williams Front Sight Pusher is the easiest and best way to install a front sight in a ramp. Equalizing the pressure on ramp and sight, it permits installation without marring or damaging. Eliminates excessive pressure on the ramp. Smoothly, accurately moves sight into exact position. This is only for a ramped front sight and will not work on any pistol sights.
