Rifle Adjustable Fiber Optic 5/16'' Wgos Rear Sight Green

The Rifle Adjustable Fiber Optic 5/16'' WGOS Rear Sight in Green by Williams Gun Sight represents the gold standard in precision iron sights for law enforcement, military, and civilian marksmen who demand reliability without compromise. This rear sight addresses a critical need: delivering fast target acquisition and consistent accuracy across variable lighting conditions where traditional blade sights falter. Whether you're running duty rifles, precision platforms, or training carbines, this fiber optic system bridges the gap between legacy iron sight ergonomics and modern luminous aiming technology.

The green fiber optic element gathers ambient light and channels it through the sight notch, producing a bright, self-illuminating aiming reference that requires zero batteries and no activation—it works instantly in dawn, dusk, and overcast conditions where your pupils struggle. The 5/16'' aperture width provides an ideal balance: wide enough for rapid target engagement, narrow enough to support precision shooting at extended distances. Williams Gun Sight's WGOS (Winged Ghillie Optimized Sight) geometry incorporates protective wings that guard the fiber bundle from impact damage and snag during weapon handling, while the fully adjustable elevation and windage mechanism allows shooters to zero for their specific load and distance requirements with audible clicks and repeatable adjustments.

This rear sight excels on AR-pattern rifles, M-series platforms, and any firearm with Picatinny rail infrastructure or standard dovetail mounts compatible with 5/16'' footprints. Law enforcement and military units appreciate the rugged, maintenance-free design—no LED failures or battery changes in the field. At 0.06 lbs, it adds negligible weight to your rifle while substantially improving sight picture clarity under real-world conditions. Installation is straightforward; ensure proper mounting torque and verify zero before duty use. The green fiber performs exceptionally well in low-light environments where red fiber optics fade, making it the preferred choice for duty rifles and night-capable platforms.
