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.

Very clear glass, and this 3x24 model stands out as being very lightweight. This weight savings is why I chose it for my recce build. Eyebox may be nominally less forgiving than some bigger and heavier acog models, but I did not notice it nor did I have any difficulty in that regard. As with all acog’s, you might have to use electrical tape over the fiber optic if the direct sunlight being gathered into the reticle is too intense. At this point in my life I own several of the trijicon acog fixed power scopes, and I’ve never been disappointed. Just be sure you buy the model with the correct reticle matched to the ammo you’ll be using. I know all the kids these days want LPVO’s on their rifles, but you’d be surprised how far you can reach out with just a little 3x optic (hint: multiply the distance you can hit with irons by 3). For the 55gr 5.56x45, that distance pretty much matches the effective distance of the round.
