What is an ACOG Scope?

The Advanced Combat Optical Gunsight is a series of telescopic sights designed and manufactured by Trijicon. ACOG was originally designed for use on the M4 carbine and M16 rifle, but the company recently developed accessories for other firearms.

ACOGs usually have a fixed magnification, but Trijicon offers several magnification levels. This makes it easy for one to find the exact magnification they are looking for. Eliminating variable magnification minimizes the number of movable parts, making these scopes more durable.

ACOG scopes use red dot aiming reticles that are slightly different from other optical on the market. The need for battery is completely eliminated by incorporating tritium in the fiber optic cable, which illuminates the reticle depending on how much light is available.

These scopes also have a bullet compensated reticle that further boosts the accuracy. They are made from aircraft grade aluminum for maximum ruggedness and durability. ACOG scopes are designed to be waterproof up to 100 meters and their virtual indestructibility makes them popular in the United States Military.

How to Select the Right ACOG Sight

No one scope is best for everything. Some AR15 ACOG scopes are good at several things, but compromises are inevitably forced by the laws of physics and optics.

This is why it is important to ask yourself what kind of scope is ideal for the specific kind of shooting you do before embarking on a search.

Killing gophers on the ranch will require a different scope as compared to snipping at 600 meters or shooting at 100 yard targets.

Below are key considerations to make when shopping for an ACOG sight for AR15…

Magnification

ACOG scopes usually have fixed magnification, which isn’t much of a surprise considering the role they are designed for. Most models have 1X magnification and some have a higher magnification, but it rarely goes above 5X.

The ideal magnification will solely depend on the situations you will shoot in. A 1X scope will offer a wide field of view if the shooting is up close and personal. Higher magnification is something you will probably be interested in if you want to make medium to long range shots.

Rail compatibility

There are different types of rails used on shotguns, handguns and firearms. Some models have integrated rails for mounting, but you may have to spend extra to purchase a mounting base if your scope doesn’t come with one. You will want to make sure that the ACOG you purchase is compatible with the rail on your firearm.

Material

ACOG scopes have a rugged design and are built to last a long time. Considering you may use your ACOG scope on a tactical weapon where there is a high chance of it being knocked down, it is important that the scope be made from a sturdy material that can withstand abuse. The material should also be relatively weight. The best options include aircraft grade aluminum alloy and magnesium alloy.

Brightness and battery life

If you are going for an ACOG clone, you should know that clones don’t utilize tritium to adjust brightness level. They use a lithium battery for power, and this is a cheaper option for someone who can’t afford an authentic ACOG scope.

It is important that you check the listed battery life. Most ACOG clones worth purchasing have a battery life if 100-500 hours if managed properly. Due to the fact that an illuminated reticle is one of the most important features of a scope, battery life is an extremely crucial factor to consider during purchase.

Types of reticles

There are different types of reticles used on ACOG scopes including crosshair and BDC. Crosshair is the simplest reticle design and is made up of horizontal and vertical lines that meet at the center.

It is particularly useful for adjusting windage and elevation. All you have to do is hold the holdover mark over the target or use the windage marks to lead a target moving at a consistent pace across the scope.

A bullet drop compensator reticle uses specific types of holdover marks and has a series of secondary marks that run down the vertical line. They allow one to compensate for ballistic curve of a bullet in trajectory over longer ranges.

Mildot reticles resemble crosshairs with a string of beads across them. The mil dots are placed 1milli radian apart and are the preferred option for military sniper use.

Price

Authentic ACOG sights made by Trijicon are pricey and cost more than $500 to well over $1500.  If you would rather purchase a cheaper option, there are ACOG knockoffs that sell for less than $500. This is an option we only recommend for casual users who don’t partake in long range shooting.

Additional tips for buying an ACOG sight for AR15 are listed below:

  • check
    More expensive scopes are better since they are built to more precise tolerances with better materials and optics.
  • check
    There is no need to purchase a scope that outrages the ammo you shoot.
  • check
    Larger objective lens gather more light, hence a brighter sight picture for you.
  • check
    -A large tube allows for increased light transmission, hence more adjustment for elevation and windage.
  • check
    Lower magnification provides a wider field of view and allows you to acquire the target easily while keeping an eye on the situation around it.

Final Verdict

Finding the best ACOG scope for your AR15 is not always an easy task.

It becomes easier when you know good selection criteria and can compare different models side by side.

Thankfully, our post above has everything you need to know about the ACOG and how to find one that matches your specific needs and expectations.
