Your advantage comes from the tritium illuminated scope technology that glows in any light, ensuring seamless transitions from shadows to sunlit vistas. Embrace optics engineered to endure.

Experienced marksmen, tactical shooters, and professional operators who demand reliable performance in low-light environments will value the Trijicon ACOG TA01NSN’s battery-free illumination and rock-solid durability. With a 4.8 / 5.0 average rating from 370 verified users, 76 percent awarded five stars for its unwavering clarity at dusk and dawn. Whether you’re on a pre-dawn hunt or securing perimeters under fading light, this 4x32 tactical scope delivers confidence where it counts.

This optic is less suited for casual plinkers or beginners seeking forgiving eye relief. Users with less-than-ideal mounting setups often struggle with its short, unforgiving eye box and fixed height, limiting comfort for those not accustomed to its tight cheek weld. If quick adjustment and variable magnification are your priorities, consider a scope with a broader eye-relief envelope and zoom capability.

4× magnification, 32 mm objective lens — delivers bright, detailed 4x32 tactical scope performance for precise target identification from CQB to mid-range.

Tritium illuminated scope technology — battery-free amber glow ensures instant aiming point in any light, enhancing low-light engagement confidence.

BDC reticle calibrated to .308/7.62 — built-in bullet-drop compensation out to 800 m lets you range targets without time-consuming adjustments.

Rugged forged-aluminum housing — waterproof, shockproof, and fogproof construction withstands extreme conditions so your optic never fails under fire.

1.5″ eye relief with BAC — optimized Bindon Aiming Concept enables both-eyes-open shooting for unmatched situational awareness and rapid target transitions.

Integral TA51 thumbscrew mount & backup iron sights — quick-attach Picatinny mounting plus flip-up sights provide redundancy and fast deployment in dynamic scenarios.

Strengths: Outstanding clarity with multi-coated lenses for maximum light transmission and zero distortion ensures precise target identification in low light and bright conditions. Rugged, forged-aluminum housing is waterproof, fogproof, and shockproof, battle-proven across decades of combat deployments. The tritium illuminated scope technology delivers a reliable, always-on aiming point without batteries, enhancing confidence in every engagement.

Limitations: The 1.5″ eye relief and narrow eye box demand exact cheek weld and precise mounting, offering little forgiveness for rapid or unorthodox shooting positions. Fixed 4× magnification, while dependable, lacks the versatility of variable-power optics, limiting optimal performance across both ultra-close quarters and extended ranges.
