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.
Designed specifically for law enforcement and military applications, the Trijicon ACOG® 3x30 (Advanced Combat Optical Gunsight) riflescope offers the right combination of ample magnification, low light capability and long eye relief for users who need fast target identification and maximum situational awareness. Equipped with the Bindon Aiming Concept (BAC), the ACOG 3x30 allows users to keep both eyes open while engaging targets.
The 3x30 ACOG model is designed for law enforcement and military applications- where the combination of ample magnification, low light capability and long eye relief make the TA33 the Trijicon ACOG of choice. This ACOG scope features Dual Illumination Green / Red Chevron .223 Ballistic Reticle, Green Horseshoe/Dot .223 Ballistic Reticle or Green / Red Crosshair 300 AAC Blackout Ballistic Reticle for subsonic and supersonic rounds.
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.
