I checked headspace before shooting at it would not close on the gauge but now it does unfortunatelySecond on calling the manufacturer and seeing what they say.
then I would see how the gun does with a “field” gauge, and possibly a different no-go. Is this the first time headspace has been checked? Source a different bolt and check headspace? A bolt swap COULD be an easier and cheaper fix if the trunnion isn’t damaged (if combloc forged trunnion that’s unlikely to be your problem, but I think some of the new commercial polish parts were cast trunnions)
I know I'll probably catch flak for this, but I've never worried about checking headspace on any of my guns.
Just to put your mind at ease. Take a fired case from your rifle and put an empty 38 special case over the bullet and with the open neck resting on the shoulder. Now, take a measurement of the two cases so nested. Now do the same with an unfired 7.62x39 case of the same head stamp as the fired case. Now you have a number that relates to the chamber depth. It is not real science, but it gives you an honest comparison.
Or better yet do the same measurement with your no-go gauge. If you are looking at less than .010 and are shooting steel cases and not reloading I'd live with it.
It sounds complicated, but it's really pretty simple.
Then I will say it again. WBP Was making cast trunnions and sending them in new commercial kits, is there evidence that your front trunnion is cst? Deformation, damage, locking recesses pushed back? Damage to the front of the receiver or the bolt?I checked headspace before shooting at it would not close on the gauge but now it does unfortunately

And I wouldn’t, nor Haven’t on factory built guns of a good, known pedigree, OP has a parts kit build, on a commercial parts set (WBP Rogaw and not Radom military parts) with what could be a cast trunnion. AKs with cast trunnions tend to do funky things at higher round counts; see IO, century Ras47, Riley defense etc. or think of it like an AR with a cast barrel extension, potentially a bad thing with dire consequences.I know I'll probably catch flak for this, but I've never worried about checking headspace on any of my guns.
Well, forgot that in my factory build, imported not kit built list.I'm glad I have a Maadi. That is all.
It does not appear the trunion has anything wrong with it at this point. I can buy a wasr trunion from apex if need be. I have a new barrel, bolt and little pieces on the way. I just dont know who in indiana besides difinitive that will do the job.
