HOLOSUN HE507K-GR X2 Red Dot Ref... vs TACTICON (TM) Predator V1 Red Do...

This is the best green/red dot i have ever tried. The reticle is sharp and quite useful. Normal red dot optics become a starburst for me due to my astigmatism.

I’ve tried a romeozero and a viper, both are a giant blur or starburst. Plinking cans at 25 yards is fun. I have a he510c mounted on a cz scorpion evo and like it a lot.

The sight has an absolutely horrible parallax effect. There is also a lot of light refracting from the red or green dot on the left side of the optic that distorts a clear view. Another negative thing to mention is a reflection artifacts the dot leave...  Read More

The latest version of the panzer ar 12, is not anymore compatible with this sight. The screw diameter is too large for the panzerar 12. The biggest disappointment is the mount. It takes up a lot of space on the rail with the whole kit.

The focus on the magnifier *. The nut ends up backing off an becoming loose and destroying any zero.
