Great information, thanks. I own both Zoraki Hp01-02 guns, honestly great and rock solid guns. 01 is my opensight practice pistol never thought about using optics. However the more powerful HP02 with a stock always itches me to learn about its long range capabilities. I have a cheap chinese red dot and a nice wrangler silencer from a local maker here in Turkey. Thinking about using them after l read this topic. I'm in doubt about holding zero of any optics in zoraki since you have to move the mechanism two-four times everytime that has an optic attached . Any experiences or advices?
