With over one million produced, Trijicon’s Advanced Combat Optical Gunsight, better known as the ACOG has become iconic in the realm of combat optics — and for good reason, the ACOG has an unquestioned reputation for quality and reliability. The Trijicon ACOG is the official medium range weapon sight for both U.S. Special Operations Forces and the Marine Corps as well as being the optic of choice for law enforcement agencies across the country. What sets the ACOG apart from the pack is what it offers to its users, increased hit potential regardless of light conditions. This is due to the tritium/fiber optic illuminated reticle found in most Trijicon ACOG riflescopes, this automatically adjusts illumination of the reticle based on available light. With a wide array of magnification levels, reticle designs, and reticle colors available — there truly is an ACOG for every mission.

Trijicon ACOG riflescopes come in the following magnification levels:

1.5x16, 1.5x24, 2x20, 3x24, 3x30, 3.5x55, 4x32, 5.5x50, and 6x48.


Superior Quality Glass Lenses
Multi-coated lenses provide superior clarity and light transmitting capabilities with zero distortion.
Rugged Aluminum-Alloy Housing
Forged 7075-T6 aircraft aluminum-housing provides for a nearly indestructible sighting system.
Fixed Magnification
Less moving parts than a variable optic equals increased durability and reliability. Seven magnification levels are available.
Waterproof up to 100 Meters
Dry-nitrogen filled to eliminate fogging. Five times more waterproof than military standard requirements.
Both Eyes Open Design
The ACOG can be used as a CQB sight when shooting both eyes open utilizing the Bindon Aiming Concept.

Got the optic in short order. Unfortunately the Acog I received appeared to of been used. It had marks on the housing and specs on the inside of the objective glass. Looking at the Prisms on the inside I saw more fingerprints than a $1000 optic should have along with a white smudge? I contacted Euro Optics and they got me squared away. Sent the first one back and got the second one. A much finer example. I'm fairly certain the first one was used or previously returned as it was missing the lens brush and the second unit had a lens brush. Not sure what to think about this since Trijicon is known for quality and Euro has always been stellar to work with/order from. I always tell my friends to look on EuroOptics before buying anywhere else. Hope they have good experiences. As for the actual optic, the crosshairs are soo crisp. Can't wait to drive tacks at the local range.

Bought this optic about 2 years ago when the price was under 900USD. In the military we had chevrons and never liked them. The crosshair is much better. This thing is just boringly reliable. Just get it. I wanted the red crosshair TA02 but those things are difficult to find.
