In this article, we will find out the difference between Aimpoint ACO vs Aimpoint pro.
For this comparison, I have tested the product for over a couple of days and have come up with a lot of findings.
Aimpoint has earned a top reputation in the field of red dot optics through the production of high-quality products.
When the US Army transitioned from iron sights to red dot sights, Aimpoint began to develop products for both law enforcement and civilian use.
Shooters appreciate this brand for its durability and quality, which allows it to perform well in real-world situations.
You don’t have to read another blog to find out the difference between these two optics.
Now lets find out, which one is the best when it comes to its durability, quality and battery life.
Here you go!

Now, let’s dive into the detailed comparison of the Aimpoint ACO and Aimpoint PRO.
GLASS CLARITY & RETICLE:
Both the Aimpoint ACO and PRO have excellent close-range accuracy (150-200 yards), but the Aimpoint PRO outperforms the ACO. The PRO has a multi-coated lens that reduces glare and reflections, and it is parallax-free, which means the reticle is always centered and focused, improving accuracy at long ranges. The ACO has a 38mm diameter objective lens and a 2 MOA red dot reticle, which is sufficient for beginner shooters to aim accurately.
BATTERY LIFE:
Battery life is an important factor to consider when choosing an optic. The Aimpoint PRO has a 2L6 battery that can last for 30,000 hours without any issues, which is more than three years of continuous use. It also has six settings for daytime brightness and four for night lights. The Aimpoint ACO has a lithium-ion battery that can last up to 10,000 hours at a higher brightness. It uses a single DL1/3N battery, which provides about one year of usage. However, the ACO’s battery will need to be replaced more frequently.
DURABILITY:
Both the Aimpoint ACO and PRO are made of aluminum and are built to withstand harsh conditions. The ACO is waterproof up to 150 feet and can withstand extreme temperatures, making it suitable for civilian use. The PRO is even more durable, with a waterproof rating of 150 feet and the ability to withstand even more extreme temperatures. It is also shock-resistant, making it suitable for military and law enforcement use.
FIELD OF VIEW:
The field of view for both the Aimpoint ACO and PRO is unlimited, meaning there is no obstruction to the shooter’s view. This is an important feature for both target acquisition and situational awareness.
MOUNT TYPE:
The Aimpoint ACO comes with a removable spacer that allows it to be mounted on a variety of rifles, including the AR-15. It also comes with a Picatinny mount. The
