Trijicon
The Trijicon ACOG 3.5x35 sits in a sweet spot that a lot of serious shooters gravitate toward - enough magnification to stretch your effective range well beyond what iron sights allow, while keeping the wide field of view that makes fast target acquisition at closer distances feel natural. The TA11-D-100557 runs on Trijicon's fiber optic and tritium illumination system, meaning the reticle stays lit and usable in any lighting condition without a single battery in the optic.
The red crosshair reticle on this Trijicon TA11 gives you a clean, precise aiming point that works well across the full range of distances the 3.5x magnification covers. Calibrated for .223/5.56, the stadia lines in the reticle handle bullet drop compensation so your holds stay accurate at distance without mental math under pressure. The crosshair pattern suits shooters who prefer a traditional sight picture — particularly those transitioning from magnified hunting optics or precision rifle backgrounds who want familiarity in a combat-ready package.
While the 4x32 ACOG leans toward precision at distance, the 3.5x35 configuration offers a slightly larger objective lens and a field of view that rewards faster shooting. It's a configuration that performs well across patrol rifle, designated marksman, and hunting applications - versatile enough that it doesn't feel like a compromise in any direction.
The Colt knob mount drops straight onto a flat-top receiver with no adapters needed. The forged aluminum housing holds zero through hard use, recoil, and field conditions that would shake lesser optics loose.
Long-range shooting for the military has been made easier thanks to the Trijicon ACOG/RMR Combos. ACOG/RMR combos provide the up-close target acquisition for close quarters/CQB in addition to long-range targets.
This dual-sighting system gives the shooter a distinct tactical advantage with the option of either the Trijicon ACOG or the RMR Sight. With the quick target acquisition of the RMR Sight or the precise aiming capabilities provided by the magnified Trijicon ACOG, the shooter has the ability to select the proper aiming solution for the situation at hand - truly the best of both worlds.
Powered by Trijicon’s patented fiber optics and tritium-based technology, Trijicon ACOG/RMR scopes can feature a multiple reticles and configurations. To further improve target acquisition and hit potential, Trijicon ACOG/RMR scopes incorporate Trijicon’s Bindon Aiming Concept – which allows for both eyes open for aiming. A Trijicon RMR sits on top, and can feature several different sizes of aiming dot.
