Simple and easy to adjust the rifle’s power level:

You can adjust the rifle’s power output for the bigger task by simply turning the hammer spring adjuster using a 1/4″ hex key, clockwise to increase the pellet velocity.  And when less power is desired such as when shooting in the backyard, just plinking around, wanting more shots per fill, or a quieter shooting rifle, adjust the hammer spring adjuster counter clockwise for less pellet velocity.
