Williams Adjustable Ghost Ring Fiber Optic Sight Set, Ruger Mk II/III/IV Bull Barrel

The Williams Gun Sight Adjustable Ghost Ring Fiber Optic Sight Set (Williams part no. 676043) is built specifically for Ruger Mk II, Mk III, and Mk IV bull-barrel pistols, replacing factory irons with a click-adjustable ghost ring rear and a fiber-optic front blade. The wide-aperture ghost ring rear sight gives a fast, natural sight picture for rapid target acquisition, while the fiber-optic front bead brightens the front sight reference in daylight. Machined from steel, the set holds its zero under repeated recoil and range use far better than a stamped or polymer sight. It’s a popular upgrade for Mk-series .22 pistol owners who want a faster sight picture for plinking, small-game hunting, or informal competition.
