I don't have any but if you have a micrometer and some packing tape you can make your own in a pinch. Might want to Google it for better instructions but basically you measure your ammo length add tape over the primer side to add the few 10ths of a mm needed to make a no go(or field) gauge and check the headspace normally. Probably not the best method but it's how I was taught to do it with aks and as long as you know the correct measurements the gauges are supposed to be it can be pretty damn close
I do, although it probably won't help, since I am in Sparks.
You really don't need a GO, if you have ever chambered a round it is above minimum. Even if it closes on a NOGO, doesn't mean it is bad, what you really need is a FIELD gauge. If it closes on a FIELD it is excessive.
