What Is An ACOG Scope Sight? (Answered)

It all starts with one simple question: What is an ACOG Scope? Watching an action movie, what’s the first thing you notice? Does your attention center on the protagonist firing off rounds as his life depends on it? Does your mind’s eye immediately jump to his gun?

Do you even consider what sight this fictional action hero has equipped himself with? For the vast majority of us, I would wager that the answer to that last question is a resounding no. But anyone involved in shooting, whether as a hobby or a profession, would be eager to explain the error of your ways.

Weapon sighting systems are one of the most fundamental components of any shooter’s arsenal. After all, you can’t hit what you can’t see. In many cases, even the slightest optical advantage can mean the difference between a kill and a miss, between life and death.

And so, in this brief article, we hope to answer any and all questions about one of the most popular weapon sighting systems on the market today.

What Is An ACOG Scope Sight?

Before we get started, allow me to provide a rough breakdown of what an ACOG scope is, for those of you completely new to the world of firearms and firearm accessories. An ACOG scope is a fixed magnification weapon sighting system manufactured by the American company Trijicon.

It stands for Advanced Combat Optical Gunsight and that’s exactly what it is. Constructed out of the highest quality materials, it is the most common sight equipped by our men and women in uniform. The ACOG is a tried and true platform trusted by those who put their lives at risk on battlefields around the globe.

What, you may ask, is the difference between a fixed magnification sight like the ACOG, and a variable magnification sight like those used by hunters and marksman the world over?

The answer is quite simple actually; a fixed magnification optics system such as Trijicon’s ACOG provides only one magnification setting. While Trijicon provides a wide range of magnification options across their ACOG product line, were you to buy a 4x ACOG scope you would be completely limited to 4x magnification. That is, the magnification is not adjustable: fixed if you will.

On the other hand, a variable magnification optical system may allow for two or three different settings. And while arguments can be made for fixed and variable magnification alike, when it comes to the former there is no contest; Trijicon’s ACOG scope is the best on the market today.

What’s The ACOG Scope’s Primary Function?

Originally designed for use with the American M16, Trijicon’s most popular sighting system has since been employed for a wide range of uses across a multitude of platforms.

Regularly equipped to M16 and M4’s in a non-civilian, combat setting, the ACOG continues to find uses off the battlefield. From hunters to hobby shooters and collectors alike mounting this scope on their AR15, the ACOG’s dominance of the fixed-sight market is proof enough of its versatility and durability.

While Trijicon’s ACOG sight can run on the higher end of weapon accessories, with prices ranging from one to three thousand dollars, for the avid shooter there really is no alternative.
