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.
Red Crosshair Reticle, M16 Carry Handle Base, Tritium / Fiber Optics 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.
The Trijicon ACOG® 2x20 riflescope is well-suited to firearms with limited space, like UZI, H&K or MP-5 9mm submachine guns. With a step-up in fixed magnification, this illuminated reticle riflescope increases target detection ability out to 200 meters in any lighting conditions.
This is the most compact unit. It is a step up in magnification and is well suited to limited space on a weapon like the UZI, H&K, or MP- 5 9mm sub-machine guns. It further increases the ability to detect and identify targets out to 150-200 meters.
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.
