I have an original Williams Foolproof Model FP-99 Receiver sight for an older lever safety Savage Model 99 that is NOT drilled and tapped for scope mounts. It uses existing holes on the back of the receiver and does not require any stock modifications. The sight is in excellent condition. It is missing the screw in aperture, but functions just fine as a hunting sight without it. Apertures are still available if desired from Williams.
Also included is an XS white stripe front sight of the correct height, plus a slot blank for filling the original rear sight dovetail after removing it.
This sight has not been made for many years and is hard to find. The present manufacture Williams Foolproof for the 99 only works on the drilled and tapped later versions. $105.00 TYD.
