The Scope That Changed Everything

There's a reason the Trijicon ACOG® (Advanced Combat Optical Gunsight) is the official medium-distance engagement optic of the Marine Corps and U.S. Special Operations Forces.

And there’s a reason why more than one million ACOGs have been produced. Every feature of its innovative design was chosen for a single purpose: to provide increased hit potential in all lighting conditions. This is possible through a brilliantly illuminated reticle pattern, a compact design, and legendary durability that continues to lead the industry.

ALWAYS ON, ALWAYS READY

Most ACOG® models are battery free, featuring a tritium/fiber optic illuminated reticle that automatically adjusts the brightness based on available light.

TAKE CONTROL

Several ACOG models are designed with a user adjustable brightness setting powered by a single AA battery. The 3.5x35 LED and 4x32 LED models both offer six adjustable brightness settings.

RUGGED, RELIABLE HOUSING DESIGN

Fixed-power design allows for minimal moving parts to create a nearly indestructible sighting system.

“BOTH EYES OPEN” DESIGN

“Both eyes open” shooting using Trijicon's Bindon Aiming Concept™ (BAC) feature allows for improved situational awareness.

OUTSTANDING CLARITY

The quality of the glass and multi-coated lenses maximize light-gathering capabilities and clear field of view with zero distortion.

EXACT TARGET DISTANCES & HOLDS

Most ACOG models feature a bullet drop compensating and target-ranging reticle for decisive aiming.

COMBAT PROVEN

No other magnified optic has been used more in combat than the ACOG.

SHOCK-RESISTANT

Proven to withstand recoil from a .22LR to a .50BMG and everything in between. Easily passes U.S. Military drop test requirements.

WATERPROOF

Exceptional waterproof performance that exceeds military standards. Dry nitrogen-filled to eliminate fogging. This optic is tested to withstand and perform in extreme cold and heat with dry-nitrogen filled housing that mitigates fogging.

INDUSTRY-LEADING RESEARCH, DESIGN & TESTING

We are engineers at heart, like our founder, Glyn Bindon. Therefore, we are bound by a commitment to seek innovative aiming solutions that constantly redefine “brilliant.” This legacy of innovation is fed by what we call The Science of Brilliant®.

“The ACOG® mounted on the M16 service rifle has proven to be the biggest improvement in lethality for the Marine infantryman since the introduction of the M1 Garand in World War II.”
