going from 18 inch barrel to 24 inch
I know I seen this answered before in another post but I cannot find it so… how much more velocity will the 24″ barrel give me if I upgrade it from my 18″ barrel??

Something like 10-15 FPS per inch I think.

What would be the limit to barrel length for getting max velocity? I read somewhere that you can’t go above the sound barrier of the gas that you are using but you can change the characteristics of the gas you are using to increase the barrier. But in general what is the max length?
