AT3 Tactical RD Review and Breakdown

The AT3 Tactical Rd is a 2 MOA red dot, and comes equipped with an incredible 50,000 hours battery, the unit like the other red dot sights, have adjustments at the top and on the side. The windage and elevation adjustments being the most difficult to customize as they need a special tool or a coin to get the correct settings for precise target acquisition.

The new advanced optical sights in the market, come equipped with either a switch or a press button, and which are embedded in close proximity with the user’s fingers for easy customization, a feature that is quite different from the At3 optical sight, which even makes it seem a bit traditional. The unit is nitrogen-filled, complete with scratch-proof lenses, and up to 11 brightness settings that you can adjust using the provided large knob on the side.

The sights are not as heavy weighing only 2.6 ounces while measuring about 2 meters long, the optical sight is available in 3 risers the first one being the zero risers, which is necessary for a co-witness, others risers are the 0.83 risers and the 1-inch riser.

AT3 Tactical RD-50 features


AT3 has been determined to hold zero perfectly but does not have the threshold to withstand the recoil shock from the 12 gauge shotgun among other firearms. The above then means that users have to be considerate of the type of weapon that they choose to use with the sight. Battery performance is, however, exceptional and users will get up to 50,000 hours at the lowest brightness settings. The windage and elevation click value has been set at 1 MOA per click while the adjustment range is +/- 35MOA.

Optical performance

The sight features a parallax-free design, and you can therefore be sure that the red dot will stay on the target and offer the perfect shot even if the shooter is awkwardly positioned. The 2 MOA red dot from the optical sight enables accurate target acquisition, and users can use the sight with both their eyes open.

The lens on the AT3 Tactical RD-50 is multicoated, meaning that users will be provided with high-resolution clear images, what’s more, is that the lens is multicoated and can, therefore, resist scratches, a feature that makes it easy to transportation and store.

Build and design

The build and design of the AT3 Tactical RD-50 is compact given the few movable parts, the finish is a matte black and you can therefore expect the sight to remain unresponsive when being used under bright light. The incorporated circuitry is shockproof, which makes the sight resistant to damage, in case of rough handling.

The optical sight is additionally nitrogen-filled, and the outside body is made of a 6061 T6 aluminum body which is very effective when it comes to resisting fogging and moisture. Out of the box, users will be provided with the rubber bikini covers meant to protect the sight and enable it achieve its full shelf life.

Waterproofing and submergibility

Waterproof optical sights are not necessarily submergible, and such is the case of the AT3 Tactical RD-50, the unit is nitrogen-filled, a feature that obliterates any chances of fogging. The sight comes equipped with the rubber gaskets on turrets and a battery cover designed which helps keep water from penetrating the sight.

A rather disappointing feature with the AT3 Tactical RD is that it is not submergible, as there are no relevant water rating information from the manufacturer, which is quite a disappointment if the sight was to be adopted for professional use. However, our attention has been brought to the incorporated O-rings, meant to enhance the sight’s waterproofing qualities. Besides the sights, rugged construction makes it waterproof.

Objective lens diameter and weight

Sights with a large objective lens diameter perform well in terms of image reproduction, and will, therefore, provide the shooter with high resolution and clear images during target acquisition. The AT3 Tactical RD-50 has, therefore, incorporated a 25mm objective lens, which rarely adds a lot of weight on the sight while providing a decent view of the field. Overall, a larger objective lens diameter is necessary for improved image quality, more especially when the sight is used in low lighting conditions.

Who is it best suited for

The AT3 Tactical RD-50 is best suited for use with most of the modern firearms, but those with a flat top Picatinny rail.

  1. Why does the red do on the AT3 Tactical RD-50 appear misshapen?

One of the most common causes of perceiving a comma-shaped or starburst reticle is because of astigmatism. But there are a couple of things that you can do to rectify the problem, for one you could try using the sight in an environment with better lighting, and instead of focusing on the dot, you could try to focus on the target by looking through the dot.

Users can also reduce the brightness of the dot to the lowest setting, where the dot can be seen clearly. Also, if you want to check and be sure of the shape of the dot, look at the dot via the rear peep or better yet, you could take a picture of the dot with a camera and you will most likely end up with the same size dot in the both described tests.
