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.
Green Chevron Reticle, Thumbscrew Mount, LED Illuminated.
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.
From the legendary ACOG® family of products, the LED ACOG is the first to offer user-selectable brightness controls. Users can select from six adjustable brightness levels with an "off" between each setting, allowing the operator to determine how much to illuminate the reticle - even in transitional lighting. Powered by a single AA battery, the LED ACOG can run for over 12,000 continuous hours (on setting #4). Like all ACOG models, it is forged from rugged 7075-T6 aircraft-aluminum, resulting in a nearly indestructible sighting system and electronics that offer outstanding reliability. Users can select multiple bullet drop compensating and ranging reticle options. Fully night vision device compatible, the Trijicon 3.5x35 LED ACOG is also compatible with most other 3.5x35 ACOG accessories available.
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.
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 The Bindon Aiming Concept (BAC) allows for improved situational awareness.
The quality of the glass and multi-coated lenses maximize light-gathering capabilities and clear field of view with zero distortion.
Exact Target Distances & Hold
Most ACOG models feature a bullet drop compensating and target-ranging reticle for decisive aiming.
No other magnified optic has been used more in combat than the ACOG.
Proven to withstand recoil from a .22LR to a .50BMG and everything in between. Easily passes U.S. Military drop test requirements.
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.
