Williams Fire Sights Features The Williams Fire Sights set s bright red fiber optic front bead measures 0.53 inches high with a 1/16 inch diameter fiber rod giving a bold easily acquired sight picture compared to a plain blade front sight. The fully adjustable peep rear sight uses a three-dot pattern with green fiber optic dots flanking the peep aperture creating sharp visual contrast against the red front bead for quick target acquisition in bright or low light. The low profile guide receiver design keeps the rear sight compact and out of the way during handling. Constructed from black anodized aluminum the sight set is built to resist wear and corrosion through regular range use and installation requires no drilling or tapping on most 10/22 models. Because the front and rear sights are dovetailed minor fitting may be needed during installation but no permanent modification to the receiver is required. For 10/22 owners who want a faster higher-visibility sighting system without machining their rifle this fire sight set is available for sale at GrabAGun.
