The TechSights 100 Set for Ruger 10/22 Rifles includes front and rear sights, which are specifically designed to be used together. This system provides a peep sight at the rear, National Match post at the front, and approximately 7.5" more sight radius than original factory sights. The TSR100 rear sight is adjustable for windage and has two flip up apertures to be used at two different distances. The front sight is adjustable for elevation. You adjust windage at the back and elevation at the front. In comparison, the Tech Sight 100 comes standard with dual apertures (.062) and is compatible with M16/AR15 apertures, and the Tech Sight 200 allows for additional elevation adjustment at the rear sight. Solid, all metal construction... You will be proud to own and use these sights! Suitable for Liberty Training Rifle and Appleseed Project. Please see our M1 Carbine 10/22 Tribute Page.
