We often get in old Winchester parts-rifles that have Model 21 front sights with a bone or antler insert. These were made from an ORIGINAL front sight that lost a blade. WE thought that we would share these old sights that will fit most of the Winchester lever-action rifles. It is the earlier number 21 front sight NO set screw. These sights fit into the 3/8 inch dovetail on the muzzle-end of the barrel and come with either a low (~.279") or high (~.40") blades. .
