Trijicon Acog 3.5x35 Red Xhr .308

The Trijicon ACOG 3.5x35 Red XHR .308 is a fixed-magnification combat optical gunsight engineered for precision rifle applications in military, law enforcement, and long-range hunting contexts. This scope combines a 3.5x magnification with a 35mm objective lens, delivering extended effective range while maintaining a compact footprint optimized for 7.62x51mm NATO (.308 Winchester) caliber rifles. The red illuminated reticle performs across bright daylight to low-light conditions without requiring batteries, using both fiber-optic and tritium illumination technology.

The optical design delivers a 9-degree field of view with generous eye relief, critical for proper shooting form under stress. Weighing 2.56 lbs with dimensions of 8.25 x 5.25 x 10.75 inches, this scope balances weight distribution across modern tactical platforms without introducing excessive top-heavy ergonomics. The bullet drop compensation reticle is specifically calibrated for the ballistics envelope of .308 ammunition, allowing shooters to engage targets at extended distances with holdover calculations built directly into the reticle pattern. Construction uses aircraft-grade aluminum with a nitrogen-filled, sealed optical tube rated for submersion, meeting military durability standards for impact resistance and environmental sealing.

This scope is purpose-built for precision rifle operators who require both close-quarters speed and extended-range accuracy. Long-range shooters, designated marksmen, and tactical teams value the ACOG for its rapid target acquisition at 3.5x magnification—sufficient for engagement from 100 to 600+ yards depending on ammunition and shooter capability. The fixed magnification design eliminates parallax shift issues common to variable scopes, improving reliability in high-stress scenarios where turret manipulation introduces handling time and potential aiming inconsistency.

Trijicon's ACOG platform is recognized across military and civilian professional communities for consistent performance in unpredictable conditions. The 3.5x magnification with .308-specific reticle calibration makes this configuration distinct from lower-magnification variants, positioning it as the intermediate option between CQB-focused ACOG models and higher-magnification precision optics. For operators requiring a durable, mission-ready scope that performs without batteries or active electronics, the ACOG 3.5x35 represents proven, field-tested technology.
