Has anyone had any issues with a PTG 7.62x39 Go Gauge?
I checked the headspace on a new AK and it didn't headspace properly. It wouldn't close on either Go or No-Go. I checked with a Wolf round and had no problem, I checked on Yugo surplus and it was a little snug but went with 1 finger. I tried many different approaches short of disassembling the bolt. I know it is recommended to check with the pin and extractor removed but I didn't. I did thoroughly clean the bolt face and chamber.
I haven't used this gauge before and once I saw this issue I checked an SKS and another AK that I know have had thousands of rounds through them and had not a single problem. Neither of them closed either.
The bolt closes as much with the Go gauge as the No-Go gauge so I am a little suspicious of the gauge rather than the firearm. I have not measured with my micrometer but will tonight. But from the looks of it, the rim on the No-Go is a little thicker whereas the length from the base of the rim to the shoulder of the gauge on the Go is actually longer. It almost seems as though Go gauge might be a Field Gauge. Is this a possibility?
I won't be firing this rifle with live ammo until it's measured but I'd like to know if anyone else had a similar experience or can add anything to my issue?
