PS: Many gunsmiths will check your headspace for WAY WAY WAY cheaper than a gauge set - some will even do it for free.
Full set would be Go, No Go and Field.
Brownells sells them.
What sizes should I be looking for and should i get .308 gauges or 7.62x51 gauges
Depends on... how specific you want to be with headspace, are you reloading, what ammo you plan on shooting (ie just 308), etc..
A few years ago I got a 3 pack which had 308 go/no go/field, and then I added 7.62 field. Those are all I have needed to this point.
