I recently put in a lurker bolt on my axe and it is operating at 200psi with my velocity sweet spotted and it is slightly louder than my stock bolt. 

My stock bolt used to operate at 180 psi with the velocity sweet spotted now it is operating at 200psi. If i put my psi down to 170 like lurker says than my fps goes down to 220- 230. can someone help me make my lurker bolt work like it should.

Have you gone through the tuning steps in the Eigenbolt manual?



1. Set pressure to ~170psi
2. Lower dwell until the gun seems to cycle poorly, and then add points until it cycles fully and crisply. In the case of any FSDO or inconsistency, incrementally add dwell.
3. Adjust velocity adjuster out until velocity begins to decrease (1.5 to 2.5 turns out with stock poppet and spring)
4. Adjust HPR to achieve desired velocity

This is almost certainly a friction issue with the spacer - Evaluate how much spacer to bolt fraction and guide to bolt friction. Making sure that the bolt deseats cleanly is critical to getting the velocity, otherwise you "run out" of dwell too fast.

I do think it is the spacer because mine has a little gap in it.  1005322_496010000492554_513857263_n.jpg?
