Hi everyone, I have a hft500 that I’m using for benchrest. I want to reduce the power slightly, is it possible to do this or do I have to take it to a dealer?
Thanks

On the right side of the receiver, just above the upper edge of the stock, you'll find a small hole with a button-head screw (2mm hex). Remove that screw and deep inside is the power adjust set screw (1.5mm hex).

Rotate the hex key clockwise (inward) to reduce the power. A small turn of the hex key (1/8 of a turn) will make a substantial change, so be judicious with the changes. Also, make sure to put on the outer screw before taking any test shots because it leaks air past the inner set screw and will change your final power output with/without the outer screw.

Best of luck.

Got it, thanks for your help.
