Please note: These will only fit the new generation SRS piston heads found in

  • Variable mass piston
  • 2018 Pull bolt kits

 

These come supplied with 3 airbrake lengths - tests with a 0.20g bb on a Sportline with M160 spring, standard piston and standard hop:

Long = 415fps
Medium = 470fps
Short = 485fps

The longer the airbrake the quieter the shot but at cost of the fps.
