The Mini Shot A-Spec M3 Micro red dot from Sightmark is a sturdy red dot with a very good price/quality ratio.
This compact red dot is extremely easy to use and is equipped with an auto-brightness feature.

Red dot/ Reflex sight

This optical rifle scope works through reflection.
If you align the weapon with your field of view, the red dot on the glass comes into view.

Because this dot is visible from a fairly wide angle and easy to align, you as a shooter are quickly on target.
With a red dot like this it is also possible to shoot with both eyes open.
These properties make this type of optic ideal for fast and dynamic shooting.

Auto-brightness

An important feature of a red dot is that the dot (the red dot that you see in the glass) is easily adjustable in brightness. This is often a missing feature among the cheaper red dots.
This is very important because you want a less bright dot in a dark environment (e.g. an indoor range).
Outside you want a bright dot so that it is clearly visible.

The Mini Shot A-Spec is equipped with an auto-brightness feature.
This red dot automatically adjusts its brightness to its environment.
For example, if you go from outside to inside, the dot automatically lowers in brightness.

For this reason, this compact red dot does not have an off-button.
When you place the protective cap on the red dot and it will turn off automatically because it is dark.

Mounting the Mini Shot A-Spec M3 Micro

The Mini Shot A-Spec M3 Micro is already suitable for optic-ready pistols with a Shield RMS-C® footprint mounting.
With the Red Dot you also get a base plate suitable for a picatinny/weaver rail.
This makes this red dot suitable for almost all pistols, rifles and carbines with these mounting options.

Durability

This red dot has a surprisingly sturdy build quality.
It can withstand the recoil of up to .375 H&H caliber firearms, is IP55 water/dust resistant and operates in temperatures from -30C to 50C.
