With rifles that do not have a regulator but have some sort of a power adjustment wheel/knob, what is being manipulated by that control? Is it simply inserting or removing a restriction similar to the screw inside the TP of the Marauder valve or does it adjust the hammer spring or something else? Just curious.James
Kratos and Akela does.

Air Arms 400-500 series do. great rifles too !!
Basically, hammer spring (and/or travel) adjustment is necessary to tune an unregulated PCP for differing pressures.... Strangling the transfer port can reduce the velocity/energy at any pressure.... The Marauder has all three!....Bob
If your definition is not simply "external", but "without tools", then I apologize for trying to help.... Bob
