The Trijicon ACOG 1.5x24 TA45-C-400334 with amber 8 MOA triangle reticle gives close-range tactical and competition shooters the legendary Advanced Combat Optical Gunsight platform in the warm amber illumination color that many shooters find naturally more visible and immediately distinguishable against certain target backgrounds - combined with the 8 MOA triangle's fast, instinctive aiming reference that requires no deliberate reticle search when the shot needs to happen immediately. The TA45 ACOG TA45-C-400334 amber 8 MOA triangle reticle is the warm-illumination configuration for shooters whose vision or specific operational environment responds more naturally to amber than to red illumination. The large 8 MOA triangle draws the eye immediately to the aiming point - filling enough of the sight window that instinctive pointing and natural eye movement bring the triangle tip to the target without any deliberate search. The Trijicon ACOG TA45-C-400334 battery-free dual illumination keeps the amber triangle lit through fiber optics in daylight and tritium in complete darkness - always on and always correctly lit, with no batteries required. The ACOG 1.5x24 large exit pupil and extended eye relief deliver the freedom of eye movement that fast dynamic shooting demands - a forgiving sight picture that stays full and usable even when shooting position and cheek weld are inconsistent during fast target transitions and dynamic movement between shooting positions. The Trijicon ACOG 1.5x24 TA45-C-400334 includes the Compact ACOG Q-LOC mount - Mil-Spec drop-test-rated 6061-T6 aluminum with one-handed, tool-free mounting and superior return-to-zero on any Mil-Spec or NATO Picatinny rail. Spring tension torque spec is 12 to 16 inch-pounds, with optional tightening to 30 to 38 inch-pounds.
