Trijicon ACOG 4x32 TA01NSN Red Triangle Reticle Rifle Scope

The Trijicon ACOG 4x32 TA01NSN delivers combat-proven optical performance with its fiber optic and tritium illuminated red triangle post reticle. This fixed 4x magnification scope provides instant target acquisition without batteries, making it a dependable choice for serious shooters who demand reliability in any lighting condition.

What Makes This Different

Unlike battery-dependent optics, this ACOG uses a dual-illumination system combining fiber optics for daylight and tritium for low-light conditions. The illumination automatically adjusts to ambient light levels, eliminating the need for manual brightness controls. The bindon aiming concept allows shooters to keep both eyes open, providing enhanced situational awareness compared to traditional scopes.

Key Features

• Dual illumination system - fiber optic and tritium powered reticle requires no batteries
• 4x32mm objective lens with multi-coated optics for superior light transmission
• Red triangle post reticle optimized for rapid target engagement
• Forged aluminum housing with hardcoat anodized finish resists corrosion
• Waterproof to 11 meters and nitrogen purged to prevent fogging
• Fits standard Picatinny and Weaver rail systems
• Eye relief of 1.5 inches accommodates various shooting positions

Field testing by military units demonstrates consistent zero retention through thousands of rounds and extreme temperature variations. The scope maintains accuracy in environments ranging from -40°F to 160°F, making it suitable for law enforcement, competitive shooting, and hunting applications. The tritium illumination provides 10+ years of usable brightness for dawn, dusk, and indoor shooting scenarios.
