I have two of the SCS-320 sights. One is mounted on an Sig Xten comp 10mm and the second one FN MK3 5.7.
The SCS-320 looks great mounted , one of the most stylish dot sights out there for a pistol.
Their performance is excellent with clear glass, clean green reticle and never shift impact even after hundreds of rounds of full power underwood 10mm loads.
With the solar system you can leave it in indefinitely never worry about batteries or having to power the sight up in an emergency.
The auto brightness works great on this model, never an issue even with weapon lights at night.
I’ve came to prefer this auto brightness feature for self defense as the dot is always ready any light condition. Simple/Stupid thought process it just works.
A tip If you desire a dimmer dot for sighting in U can place a small piece of tape over the solar panel and it dims to a small precision dot perfect for range time. I prefer this for sighting in, but like a brighter dot for self defense.
Overall, I had concerns buying this SCS model sight, mainly the auto brightness and rechargeable solar battery. No worries anymore those are two of the best features I see now.
