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.

The optic is clear, bright and easy to use. It's solid, and it's easy to repeatably position on the rifle. Aside from the relatively short eye relief - which is no surprise - it's pretty close to ideal. Buying it from EuroOptic was easy, quick and surprisingly affordable. It arrived quickly as well. I can't say enough good about this experience.

Shipped fast and came quickly very happy with this product. Quality is amazing. The only downside to some people is that the FOV is small but if you don’t mind it it’s not bad I personally don’t care but others have their own preference.

Shipped fast and arrived quickly. Very happy with it. Good clear sight quality is amazing and good FOV. The only downside maybe is the eye relief is small but if you don’t mind it it’s not a big deal.

Can't say enough good about the ACOG and euro optic. I wish it came with the pouch but it doesn't matter, I won't take it off the rifle anyways. Thanks for the outstanding service.
