Trijicon 3.5x35 ACOG Dual Illum Red Crosshair .223 Reticle w/Colt Knob Mount - LED 3.25 MOA Red Dot RMR Type 2 TA11-D-100557

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.
