help please

I was workin on my flyed 4 yesterday, and put the LPR guage on. I turned on the air, and fired dry.

The gun acted like it chopped a ball. The bolt got jammed in the breech.

I took out the bolt and fired it without the bolt, and watched the ram work, and it worked fine, so my conclusion is that the bolt is bent.

Is my analysis correct, or is there another possibility?

What was your LPR pressure?

normal, 5 1/2 bar

try §§§§ing around with the LPR and/or dwell times. i have heard the rare occasion of bolt stick without reason before. happened to me personally once but i was running the LPR really low.

if you cannot find anything, call/viset the people who did your mod. they may have done something during the drilling, etc of the new parts. what you could also do is take out everything in the breech except bolt (eyes, feedneck, detents, etc) and try firin a few times.
