Description

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.

Features:

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.

Fantastic optic if you're looking for something in this magnification range that is easy to use. I have mine mounted on a SIG 716i .308. It looks big, but with an RMR mounted on top it weighs the same as an LPVO in a mount. Reticle is easy to use. Glass is fantastic and comparable to any European optic in the same magnification range. Comparing the 5.5x ACOG to a 6x LPVO you cannot see the difference in magnification. Low light performance is where this really shines. There is no LPVO out there that can touch the TA55 in terms of low light performance. Like all ACOG reticles these are in meters not yards. Prior to purchasing this, I contacted Trijicon to learn about the subtensions for the reticle. The reticle is calibrated for 175gr .308 at 2650 FPS, however Trijicon advised the difference in loads is often less than the width of the lines on the crosshair. The subtensions for this reticle are the same as those for the TA11E (Chevron 308 reticle) so you can find that chart online. Running this reticle through a ballistic app, like Strelok or Chairgunner, I learned M80 ball at 2600 FPS (which is expected out of a 16" barrel) almost perfectly matched the reticle when you use yards instead of meters. Testing on the range confirms this. So if you're looking to bang steel out to 500 yards with M80 ball out of a 16" rifle, this will work fantastic for you. Additionally if you're using different loads you can get the BDC exceptionally close if you zero at 300 on the 300 mark. Overall I would highly recommend this optic if you're looking for something in the 6x range that has a functional BDC and fantastic low light performance.
