What headspace gages should I get? They will be used on aks and maybe a rpd. Thanks
Clymer is what I use.
Doesn't really matter, just the appropriate caliber headspace gauges are necessary. Unless you are asking of the 3 types, then the "go" and "no-go" gauges. There are threads that have covered this already in greater detail if you want to just look for them.
I got mine from Curtis but Gunbroker has them also....
