The Troy Folding Rear Tritium Sight in Black is a rail-mounted backup sight system engineered to provide reliable point-of-aim in low-light and no-light environments where standard iron sights fail. Tritium self-illumination technology emits a continuous glow without batteries or external power, making this rear sight a permanent operational backup that eliminates dependence on tactical lighting or electronic systems during contingency scenarios.
The rear tritium sight features a folding design that allows seamless co-witnessing with primary optics and keeps the sight profile low when not in use. The compact form factor—measuring 6.25 inches in length with minimal sight radius depth—fits standard Picatinny rail systems across all rail lengths. The serrated aperture and tritium dot references ensure rapid target acquisition in twilight, dawn, and complete darkness. The black finish resists corrosion and glare, making it suitable for field environments where standard A2-style sights or ironsight systems would be replaced by this lighter, more flexible alternative.
Law enforcement officers, military personnel, and serious rifle shooters deploy tritium rear sights for patrol carbines, entry weapons, and precision rifles where low-light performance is non-negotiable. This sight is commonly paired with primary optics, magnified systems, and co-witness front post configurations to create redundant aiming systems that function when electronics or batteries cannot. The 0.25-pound weight adds minimal mass to the upper receiver and preserves balance during extended operations.
Troy Industries tritium BattleSights represent an established choice among operators who prioritize failsafe sight systems. The folding rear configuration is a standard specification for carbines in professional service where mission-critical equipment must remain operable across all lighting conditions and environmental stress. Tritium technology delivers consistent illumination for 10+ years, making it a true set-and-forget backup sight system.
