Mid-range magnification and quick BAC target acquisition makes this an ideal choice for hunting and law enforcement.

Advanced Combat Optical Gunsight—Hit Fast in any light. Designed for use with the M16 family, every feature of the ACOG mechanical and optical design was chosen for a single purpose: to provide increased hit potential in any light, and under the toughest combat and tactical conditions—without failure-prone batteries. Rugged, dependable, and battle-proven, Trijicon ACOG systems are internally-adjustable, compact roof prism telescopic sights with battery-free dual illuminated reticles, powered by a patented combination of fiber optic and tritium-based technology. A Trijicon ACOG can measurably increase your ability to make faster “instinctive” shot placements with marksman precision—day or night. Plus, ACOG systems offer Trijicon's exclusive Bindon Aiming Concept™, an innovative both-eyes-open aiming method that uses scope magnification for quicker target acquisition in any light. It provides a huge advantage with fast moving targets, especially during stressful, low-light situations.
  • NEW: Highly visible Green illuminated reticles enhance Trijicon’s innovative both-eyes-open BAC aiming method
  • Mid-sized 4x32 scope with long eye relief; and large field of view
  • Faster target acquisition at medium-to-long range, ideal for high-speed competitive shooting
  • Dual-illuminated reticle is visible in any light, without batteries
  • Military-grade aluminum alloy housing makes ACOG nearly indestructible, waterproof to 500 ft.
  • Reticle choices: Green Donut

This versatile version of Trijicon’s primary military ACOG is a favorite of civilian hunters and law enforcement agencies. The donut-shaped ranging reticle will never mask the target and give the shooter pinpoint accuracy out to 800 meters. Daytime illumination is provided by fiber optics and Tritium illuminates the scopes at night.


  • Bindon Aiming Concept (BAC) allows use of the both-eyes-open aiming method along with scope magnification sighting for rapid target acquisition in any light
  • Longer Eye Relief for larger caliber rifles and large exit pupil for fast target acquisition without concern for parallax error—even if you're not positioned perfectly behind the sight
  • Internally Adjustable Focus—only the prism housing moves, creating a much more rugged design than conventional telescopic sights
  • Trijicon Fiber Optics automatically adjusts the brightness level and contrast of the reticle to available light conditions
  • Aiming Reticle glows in low light conditions and is guaranteed to illuminate up to 15 years
  • Totally battery-free—ACOG delivers increased hit potential in all lighting conditions without the need for failure-prone batteries
  • Broad Band Anti-Reflective Multi-coated Lenses provide superior clarity and light gathering capabilities with zero distortion
  • Waterproof to 100 feet / 30 meters
  • Dry nitrogen filled to eliminate fogging
  • Military-Grade Aluminum Alloy Housing provides for a nearly indestructible sighting system
