EAS Elevation Adjustable Sight:
This sight has a full .5" of travel, taking it from 25 yards to 3,000 and beyond. It can completely replace the issue sight blade and be left in place for both iron sights and Diopter shooting. It is compatible with all of the other Swiss Diopters intended for the K31 rifle. The EAS sight is threaded both sides to accept the Eagle e eye magnifier of the target side and the Anschutz adjustable aperture on the shooters side.
