I take this little rascal with the gun. I can adjust fps to any weight pellet I choose to use. I chrony'd the number of turns a specific weight pellet takes to get to the fps I want. All I need to remember is what the last pellet weight setting was, and then turn it up or down to get the fps I want for the weight pellet I change to...without needing a chrony in the field.
Handy!
