Trijicon Sro Vs the Aimpoint Acro- which is the better sight


Trijicon Sro has taken over the sights industry simply because it comes incorporated with a larger sight window, a feature that enables shooters to track the dot through recoil. Aimpoint Acro on the other hand is famous for concealing all the electronic components in one sight while remaining functional.

Both Trijicon and Aimpoint have established themselves as the best sights manufacturers, Trijicon is known for producing high quality and durable sights, with durable adjustments and excellent glass quality. Aimpoint maintains some rather unique features with most of their sights, most of which are traditional but sturdy and with clear reflex sights.

During the optical sights shopping, shooters would categorize the sights with their ability to be used professionally, by the marines, or for recreation. So, to which category do both the Trijicon Sro and Aimpoint Acro belong, let us find out below.

Trijicon Sro vs Aimpoint Acro- How do they compare?

Brightness settings

Aimpoint Acro has been equipped with 4 dedicated night vision settings and 6 daylight settings, the night vision settings are necessary as they enable accurate vision in the low light conditions, more especially at night. The 6 daylight settings enable accurate target acquisition even under the glare of the sun, all you have to do is tweak the settings.

Trijicon Sro on the other hand is customizable in that you can either set it on automatic or tweak the 8 adjustable settings to achieve precision, we are, however, noting that Trijicon Sro does not have the dedicated night vision settings, which then makes the Aimpoint Acro the better unit as it is convenient for night use.   

Waterproof and submersible

Both of these sights are submersible and will not admit water inside the scope, neither will they fog up, the Aimpoint Acro can, therefore, be submerged up to 82 ft and still work efficiently, a feature that makes it attractive for professional use. Trijicon Sro only offers 10ft, meaning if you go deeper then you will experience problems, the scope is therefore not convenient for deep diving but can qualify for certain professional applications.


At 46g the Trijicon Sro is the lighter unit of the two and the most loved because the lightweight makes it easy to carry around, transition, and convenient when speed is of the essence. At 60g the Aimpoint Acro adds extra weight to your weapon, we however note that it is compact and a great sight for people who don’t mind using the tunnel sight.

Aiming Dot Size

There is a significant difference in the dot sizes that have been incorporated in these two sights, with Trijicon coming out as the best because it allows users to use up to three different dot sizes for accurate target acquisition. You will, therefore, get the 1MOA dot size which is perfect for use in situations that require enhanced accuracy at a distance.

The 2.5MOA dot, on the other hand, is convenient for many different shooting applications and can be conveniently used with a pistol. Users have also been provided with a 5.0 MOA dot, now for this one, it tends to be super effective when used on professional grounds where speed and recovery of the dot is important. Aimpoint only offers you A 3.5 MOA red dot, which will provide you with a 1.6inch circle.

  • Enclosed optical channel prevents dot from being blocked by contaminants

  • Up to 1.5 years of continuous operation (at position 6) using one CR1225 battery (included)

This has to be the simplest sight that you have seen, given its compact and tube-like structure. The above is, however, for the best because all the electronics get concealed, which then makes the unit waterproof and submersible up to 82ft. The incorporated 3.5MOA red dot will afford you a 1.6” circle convenient for faster target acquisition.

The sight is pretty easy to install and changing the batteries is seamless as you will not have to tamper with the sight. The unit can be used for hunting among other professional applications, the time of use shouldn’t be a problem given that it comes equipped with up to 4-night vision settings and 6 daylight settings, thus can be used all day any day.

Both the Trijicon and the Aimpoint sights are great sights but their applications are significantly different. Trijicon doesn’t come out as a professional unit but we cannot entirely rule that out because it has been equipped with three different red dot sizes for use with different weapons and for different applications. The Aimpoint on the other hand has all the qualities that professionals look out for, for example, it is submersible up to 82 ft, and can be used by both the day and night vision equipment, but has a poor battery life when compared to the Trijicon Sro.

Final Verdict; so which is better, the Trijicon Sro or the Aimpoint Acro?

The Aimpoint Acro is the better unit because it is night vision enabled, has a convenient dot size, which enables accurate target acquisition, and can be used by the marines given its ability to remain waterproof even when submerged up to 82ft deep.
