I bought a set of CIP standard headspace gages from Manson recently for some rifle building projects that I have been thinking about/working on. just for laughs I figured I'd check them in my d-technik/czechpoint vz58. the go gauge closed. Then to my dismay, I checked headspace with the no-go gauge and it closed right up too... when I get home later tonight, I'm going to take some shims and see how much beyond no-go it is, but this is a little disconcerting. I've had probably 2-300 rounds through this since I bought it in about 2010, one broken sear after about 50-100 rounds (looked not to have been tempered properly - stress fractured) and the sight post was loose. They sent me new parts without question, and I got it up and running again at no cost with minor inconvenience.
I'm wondering if anyone else has had issues with headspace on the d-technik VZ58? I suppose it's possible (though doubtful) that my gauges were improperly made, but I checked these on a bolt action rifle (with chinese sks barrel) that I had originally headspaced using my poor-man's gauge. First was an unfired empty case, then a live round from two manufacturers, all with a piece or two of tape on the base. The reason I don't think the gauges are out of spec/too short, is that I couldn't fully close the bolt on the go gauge, and it wouldn't close at all on the no go gauge.
Also wondering what I should do, if anything, about this? headspacing on these rifles is done, so far as I know, by getting a slightly longer locking piece. I'm going to try to check the headspace using the two other locking piece I have from kits, to see if they are any better. were these locking pieces numbered for different sizes, and if yes, what do those numbers mean?
