Shocktech Piranha / Spyder Velocity Shim Kit

Description

Perhaps a better way than changing springs to increase or lower your Spyder or Piranha’s velocity is to simply swap the shim. Shocktech is
introducing the Shim Kit which will allow Spyder and Piranha owners to adjust
their velocity in 10 fps intervals just adding a different colored shim.

• The shim kit provides 6 color coded shims, or spring
  guides.
  
• Each colored shim can be matched with the provided
  chart to see roughly how your guns velocity will be affected.
  
• An inexpensive way to drop or raise your guns velocity
  instantly.
