Features Review: Aimpoint ACO

The following are the aspects of Aimpoint ACO that will help you make an informed purchase decision.

1. Durability And Reliability

Red dot sights like the well-liked Aimpoint ACO are well-known for their accuracy and rigidity. Since the ACO has been constructed to endure difficult circumstances, it is the best option. One of the distinguishing characteristics of the ACO is its tough design, which is rendered possible by the use of premium components and innovative production methods.

The ACO is made of a light aluminum alloy that maintains strength and durability while being relatively lightweight. Additionally, this alloy has a high level of corrosion resistance. The ACO is also made capable of handling hefty recoil without losing any of its functionality because it is shock absorption in design. 

The optical system of the ACO is another aspect that adds to its robustness. The ACO is intended to function reliably under a variety of circumstances. Because of its waterproof nature, it can be immersed up to 15 feet in the water without suffering any damage. Thus, the Aimpoint ACO is a top pick for both professionals and devotees due to its reliability as well as its strength. 

Because of its tough design, superior optical system, and extensive battery lifespan, it will operate consistently and dependably under even the most trying circumstances. 

2. Reticle

The Aimpoint ACO (Aimpoint Carbine Optic) has a 2 MOA red dot reticle, which is an increasingly common option due to its ease of use. A red dot reticle is a simple form consisting of a single dot displayed on the optic lens. The shooter can acquire the desired point swiftly and accurately because they can see the dot overlaid on their target whilst they look via the scope.

The Aimpoint ACO’s 2 MOA reticle is made to offer a precise aimed point for shots from different ranges. The dot covers about 2 inches of the target’s surface at 100 yards, compared to 1 inch at 50 yards. This qualifies it for a variety of shooting applications, including close-quarters combat and farther-reaching encounters.

3. Lens And Glass Clarity

Exceptional clarity and sharpness of images are provided by the Aimpoint ACO, which is equipped with an expensive lens and modern glass technology. The multi-layer, pro-reflective coated glass used in the construction of the ACO lens diminishes reflections and offers a crisp, clear sight picture.

An image that is clearer and more visible is produced by the ACO lens’s multi-layer, pro-reflective coatings, which improve light transmission. This is particularly significant when it’s dark outside because that’s when the ACO’s optics truly stand out. Additionally, the coatings aid in lowering glare and reflection, which can be obstructing and make it impossible to see the goal.

The anti-reflective coatings and scratch resistance of the ACO lens work together to keep the optical transparency of the lens as time passes. On top of that, the Aimpoint ACO’s lens has wide-eye comfort and a great panorama view.

4. Size And Weight

The Aimpoint ACO (Aimpoint Carbine Optic) is a red dot sight that is lightweight, tiny, and convenient to put on while still being powerful and long-lasting. The ACO is a fairly compact sight that is simple to install on many weapons. Its dimensions are 4.7 inches long, 2.2 inches wide, and 3.0 inches high.

The Aimpoint ACO weighs only 6.7 ounces, which is surprisingly light for a sight that is sturdy and long-lasting. The inclusion of quality aluminum alloy within the ACO’s construction, which offers excellent durability and rigidity while keeping its mass low, is partly responsible for the sight’s lightweight design.

5. Windage And Elevation

The shooter can zero the sight for their particular weapon by using the windage and elevation modifications on the Aimpoint ACO. The point of impact can be precisely adjusted with ease and speed due to the basic and user-friendly layout of the ACO’s adjustment system.

Shooters can move the point of impact left or right by using the windage modification on the Aimpoint ACO, which is situated on the right side of the sight. The top of the sight houses the ACO’s elevation adjustment, which enables the shooter to move the point of impact upward or downward. 

Use the small tool that comes with the sight to make the adjustments on the Aimpoint ACO. A 1/2 MOA change in the point of impact results from every press of the windage adjustment. High precision is offered by the 1/2 MOA adjustments, and field adjustments are simple to perform with the provided tool.

6. Source Of Power

A single DL1/3N or CR 2032 battery powers the red dot reticle on the Aimpoint ACO. With up to 10,000 hours of nonstop use from a single battery, the Aimpoint ACO’s battery life is noteworthy. The ACO’s energy-efficient layout is partly to blame for the increased battery life.

7. Illumination Settings

Shooters can adjust the red dot reticle’s brightness for their particular shooting circumstances through the Aimpoint ACO’s red dot reticle’s flexible brightness settings.

A rotary knob located on the right side of the sight is used to change the Aimpoint ACO’s lighting settings. The shooter can select one of ten different phases on the knob to change the intensity of the dot from off to its optimum brightness.

The ACO’s illumination system is made to be simple to operate and highly versatile, enabling the shooter to select the ideal luminosity level for their shooting scenarios. Additionally, the illumination settings are made to be very effective, ensuring that the sight works even in minimal light and conserving battery life.

8. Mounting Options

To accommodate a variety of mounting options, the Aimpoint ACO uses a standard tube. Many different mounting systems can be used to mount the sight on rifles, handguns, pistols, and other weapons.

A Picatinny or Weaver rail mount is one common way to mount the Aimpoint ACO. A quick-detach (QD) mount is an additional mounting choice for the Aimpoint ACO. The shooter’s ability to rapidly and easily connect and detach the sight is made possible by QD mounts. In terms of ways to mount, the Aimpoint ACO is very adaptable.
