Shorten your trigger pull up to 50% by changing the firing point.


This part replaces the stock spool valve in the: 

Planet Eclipse- m170r, eMek, MG100 and gMek markers

  • The stock spool with a non adjustable trigger has about a 7mm* pull.
  • The stock spool with an adjustable trigger has about a 4.25mm* pull.
  • The Bang Switch with an adjustable trigger has about a 2mm* pull!!


*When measured from the bottom point of the trigger.


 The 3way spool valve works in two stages of action. As you pull your trigger back, the first stage of action shuts off air travel to the back of the bolt, preparing the bolt to cycle. As you continue pulling the trigger back, the spool enters the second stage of action. Here it releases the air from the back of the bolt, allowing the bolt to cycle.

 There is a small amount of unneeded travel between these two stages of action that the Bang Switch Eliminates. With the firing point occurring at an earlier stage in the trigger pull, there is no need for the trigger to continue past this point, so you can adjust your trigger set screw to stop your trigger from continuing to travel, hence shortening your trigger pull by up to 50%


While you do not need an adjustable trigger for the Bang Switch to change the firing point, you may not experience the full benefits without one.



**We recommend that a certified gun tech install this part.
