I have a problem that I cannot figure out. I have an ULE Custom with an X-Valve and Intelliframe. I have the switch for the warp feed in the trigger frame. When I pull the trigger, sometimes it fires, sometimes it does not. The majority of the time, the trigger is spongy and will not trip the sear.

What I have done thus far:

  1. measured the trigger rod length - validated to be 1.985"
  2. measured the on/off pin length - validated to be .750 (stock on/off pin)
  3. swapped the intelliframe with 68 automag metal trigger frame (marker cycles)
  4. adjusted regulator pressure
  5. placed valve in another marker (cycles properly)
  6. removed the switch for the warp feed


I am at a loss. Any thoughts?
