Trijicon ACOG 3.5x35 Green Horseshoe/Dot M249

Trijicon ACOG 3.5x35 Machine Gun Optic

The ACOG (Advanced Combat Optical Gunsight) represents decades of refinement in combat optics design. This 3.5x35mm variant is purpose-built for the M249 weapon system, delivering the precision marksmanship capability and close-quarters speed that define modern tactical shooting.

Key Features

• Fixed 3.5x magnification with 35mm objective lens for optimal light gathering and field of view
• Dual-illumination technology combining fiber-optic and self-luminous tritium for operation in all lighting conditions—no batteries required
• Green horseshoe/dot reticle with bullet drop compensator calibrated to 1000 meters
• TA51 Flat Top mount included for direct attachment to Picatinny rails
• Objective lens insert (ARD) included to reduce glint and reflections
• Threaded eyepiece bosses allow mounting of auxiliary optics like the Trijicon RMR for close-combat engagements

Design Philosophy

Every element of the ACOG was engineered for a single purpose: maximizing hit probability across all operational scenarios. The fiber-optic system automatically adjusts reticle brightness in daylight, while tritium provides a glowing aiming point in total darkness. This allows you to maintain both eyes open, preserving situational awareness during engagement.

The fixed magnification and compact profile make the ACOG exceptionally durable—there are no moving parts to fail when it matters most. Trusted by competitive shooters, law enforcement, and professional operators worldwide.
