Blued steel, with two eye disks, adaptor plate allows easily installation on Lyman Great Plains rifles. Two mounting screws included. Features 1/4 minute micrometer click adjustments for elevation and windage, quick release slide.

The larger 5/8" diameter knurled eye disk is drilled with the smaller .040" aperture for use on bright days. The smaller 1/2" diameter knurled disk is drilled with a larger .093" aperture for large field of view and quick target acquisition on cloudy days. Made in the U.S.A. by Lyman, this sight is a favorite of target shooters. Both large and small eye disks are included (small disk shown). A third choice is to use this sight with no eye disk installed, for quick sighting in dark woods or dark days. Lyman Great Plains rifles made before April 1997 will require drilling and tapping an 8-32 hole. Lyman Great Plains rifles made after April 1997 will have a factory drilled and tapped hole.

Shown with the 1/2" disk installed. Replacement disks are available at extra cost.
