Reply To: Fx boss shot string
I would recommend adjusting the hammer spring tension before touching the regulator. Hammer tension screw is the bottom hole with the 5mm hex socket. The screw had to be heated quickly with a butane torch to soften the loctite. Clockwise rotation increases your tension (more velocity) and its little touchy so go at 1/2 turn increments. If your not confident in doing something like this…in my opinion…just leave it alone and have fun with the rifle! That shot string looks great and there’s good possibility it will get better once you get that regulator and other parts “broke in”.
