I dont recall this being an issue before. I know scratches on the bolt are common, but shouldnt it go in smoothly and out smoothly with a few clicks of the trigger? I had to force it out!
It seems the point of resistance is at the very end of the grove that the cocking pull mechanism fits. seems like a bit of metal is sticking down into the bore.
a new designz it pretty good and inst too expensive,
you could get a rocket valve, if you're willing to put out the cash and go ahead and tune it to low pressure
