Archer Airguns

This is the Industry Brand Target Aperture Rear Sight as fitted to the AR2078/9 series of CO2 rifles and the BS4 spring gun. Fits most air rifles with standard 3/8-inch scope rails without a "hump" between the rails. The sight provides precise 1 minute-of-angle click adjustment for elevation and windage and includes an efficient rubber eye cup to minimize stray light affecting the sight picture.
