Trijicon ACOG 4x32 TA31-D-100432 300 BLK LED Green Crosshair

The Trijicon ACOG 4x32 TA31-D-100432 delivers precision optics specifically calibrated for 300 Blackout cartridges. This combat-proven optic combines fixed 4x magnification with an LED-illuminated green crosshair reticle for rapid target acquisition in any lighting condition.

What Makes This Different

Unlike variable power scopes that can shift zero, this fixed 4x ACOG maintains consistent point of impact through thousands of rounds. The dual-illuminated reticle system uses both fiber optics and tritium for automatic brightness adjustment without batteries during daylight hours. LED backup illumination ensures functionality in complete darkness when natural light sources are unavailable.

Key Features

• 4x32mm fixed magnification with 36.8-foot field of view at 100 yards
• LED-illuminated green crosshair reticle optimized for 300 Blackout ballistics
• Forged aluminum housing with matte black finish resists corrosion and reflection
• Dual-illuminated system combines fiber optics, tritium, and LED technology
• Waterproof to 11 meters and shockproof to withstand heavy recoil
• Standard Picatinny rail mounting system fits AR-15 platforms
• Bindon Aiming Concept allows both-eyes-open shooting technique

Field testing demonstrates consistent accuracy across temperature ranges from -40°F to 160°F. The rugged construction survives drops, impacts, and continuous firing schedules without losing zero. Law enforcement agencies and military units rely on ACOG optics for critical missions where equipment failure means mission failure. The 300 Blackout-specific reticle provides accurate holdovers for both supersonic and subsonic ammunition.
