Sorry if this has been answered already but this thread is a mile long. First off I am using a used X Valve with a lvl X bolt, ULT and not much for lvl X parts as it did not come with any extra carriers or springs. Warp left Ule body, AM/MM rail and an E Grip frame. My problem is that the gun will fire and not leak at the bolt but the bolt does not always want to reset all the way. I have plenty of clearance in regards to the sear and the solinoid. I have also replaced the regulator piston but it is still leaking from the velocity adjustment.
