At3 Aro Micro Red Dot Review

Products that come slapped with the lifetime warranty, do build a customer’s trust and such is the case of the At3 ARo Micro Red Dot. Among the many optical sights in the market At3 stands out for being exceptionally versatile in that it will provide you with two types of mount, the low and the absolute co-witness mount, each of which integrates with specific types of weapons.

So for the absolute co-witness, you can use it with the modern types of weapons such as the SIG Rifles, the AR platforms, and the CZ scorpion among others. And the low mount that comes with the sight can be used with shotguns, revolvers, and the Drop Comb rifles among others. Most shooters purchase their optical sights with regards to their objective, some want effective sights that they can use for hunting, others use them professionally and others for recreation.

And because of the above, optical sight manufacturers also make sights for use by the different categories of shooters; the reason why you need to put more consideration on a sight’s specs. Some of the most important specifications to look out for are such as the battery life, as you don’t want the sight bailing on you at your point of need; the levels of brightness settings, and night vision capability.

At3 Aro Micro Red Dot review and breakdown

The At3 Aro Micro Red dot is a budget-friendly optical sight sporting a durable aluminum outer body; the unit is quite easy to use when compared to other brands of the optical sights. Some of the easy to use features are the top load battery installation, which makes it easy for shooters, to access and change their battery even when in the range or hunting grounds.

The lens has been perfectly shielded, with an extended hood at the front part that protects the sight from impact and scratches. Out of the box, users are provided with two mounts, the low mount and the absolute co-witness mount which allows them to use the sight with regards to the relevant application and weapon. Special wrenches have been included in the box necessary for windage and elevation adjustments.

What’s more is that the matte black outer finish works to counter light that would have otherwise reflect on the sight, which would have consequently made accurate target acquisition a hurdle. At3 Aro Micro red dot is a simple sight but quite functional and for only $159, you will be able to carry out your expeditions with no worry about the battery life because it will give you up to 5,000 hrs but on the medium setting.

What we liked:

  • The Multi-coated lenses are scratch-resistant
  • Offers up to 6 levels of brightness
  • The viewing area is quite big
  • The sight is parallax free, ensuring that the red dot stays in sight
  • The viewing area is considerably large.

What we didn’t like ;

  • The red dot intensity tends to diminish against a white target under bright sunlight
  • Does not handle recoil very well and might therefore break

At3 Aro Micro Red Dot features

Reticle Performance

The At3 Aro Micro Red dot is a compact unit, but with a rather large viewing area and has obliterated all the bulk that comes with most standard tubes. The large viewing area enables situational awareness, and users can, therefore, use the sight with both their eyes open. And still on reticle performance this optical sight, has been equipped with the multicoated lenses, which apart from providing users with an excellent image, are scratch-resistant.

The provided dot is a crisp 3MOA, which will afford you up to 0.3 inches @ 10 yards, up to 3 inches at 100 yards, and about 1.5 inches @ 50 yards all of which are more than precise for your shooting expeditions. What’s more, is that the red dot has been configured to stay on the target if you need to move your head away from the sight.

Lastly, users get up to 6 levels of brightness settings, meant to provide the best vision regardless of the lighting conditions.

Adaptability

There are many optical sights in the market but which cannot be used with a large number of weapons. For the At3 Aro Micro Red Dot, it is highly versatile, and therefore, comes equipped with a removable low mount for the Picatinny rails, and a fast fire, mounting footprint. The user additionally gets the 83” absolute co-witness cantilever riser mount, meant to improve the effectiveness of the Ar15 when it comes to target acquisition.

While the adverse weather conditions might force you to postpone your mission, the At3 Aro Micr Red Dot, allows you to stay on even when it is raining. The optical sight is waterproof, and even after being rained on while on duty, it will not fog up and distract your view; on the contrary, the sight will remain effective allowing you to achieve precision even in the harsh weather conditions.

So while some of the shooters object to our next opinion, the sights manufacturer begs to differ thus categorically states that the optical sight has incorporated the shockproof circuitry meant to resist damage especially when exposed to impact or recoil.

Weight

Opticals sights don’t need to bear a lot of weight, as it will possibly compromise on the functionality of the weapon. The At3 Aro Micro Red Dot is a low profile optical sight that will integrate and complement whichever weapon that you want to use it with, without adding more weight as it only weighs 1.8oz.

The low weight of the optical sight means that users will not have to use much effort when transitioning between targets, they will experience minimal lag during dot recovery, and carrying the weapon in general complete with the sight is way easier.

NVD capability and brightness levels

We don’t deny that the AT3 Aro Micro Red Dot is quite effective in that it allows users to tweak the brightness levels to complement their environments thus enable accurate target acquisition. However, what is quite disappointing with this unit is that it is not night vision enabled, so for whichever application you are getting it for, be sure that your operations are centered within the day.

Battery life

If you have to work or hunt the whole day, the At3 will suffice given the extended battery life of up to 5,000hrs but on the medium setting. What’s more, is that the 6 hours auto shut off system helps in extending the batteries shelf life. A durable battery on an optical sight is one part of the equation and the missing part is how fast can you load your sight while in the field. For the At3, we can say, loading is fast because it is a top-loader kind of optical sight.

Who is it best suited for?

At3 Aro Micro Red Dot has been designed for use by hunters, and you can therefore use it on a hunting rifle, if you have a pistol slide or a shotgun the optical sight will well suffice.

Are there any alternatives to the At3 Aro Micro Red dot?

Yes, there are alternatives to the At3 red dot sight and this are the Vortex optics venom red dot sight, the Truglo dual-color multi reticle optical sight, and the Bushnell advanced micro-optical sight.

Final Verdict: So, should you get the At3 Aro Micro Red dot?

Unless you want a sight that can work effectively at night then the At3 Aro Micro Red Dot is a high-value light cost type of optical sight for use with the daytime applications. And the one interesting bit that we wouldn’t want you to miss out on, is the fact that this optical sight can be paired with At3 magnifiers, to make it more adaptable.

FAQ’s

  1. Since the sight can turn off automatically do I have to manually turn it on?

Turning on the At3 Aro sight is manual, and you, therefore, have to long-press the little button on the side; if you, however, leave your sight idling for approximately six hours then it will automatically switch off.

  1. Does the optical sight fit when used on an AR15?

The At3 Aro red dot has been configured to fit the Picatinny rail and you will, therefore, use the incorporated riser mount for the AR15. Out of the box you will be provided with the low mount but don’t screw them on too tight the first time because it could be hard to get them out.
