CIP or SAAMI headspace gauge for AK47?

[Wingshooter]

I'm about to put my Polish underfolder kit together finally. I have all he tools I need except for go/no go gauges. Should I get CIP or SAAMI? There's different opinions on the web, so I'll go with the advice I get here.

AK builder is selling the CIP, so maybe I'll go that route. Any opinions?

In an AK type weapon, the difference between the 2 is pretty much non existent. I would be surprised if the difference was more the .0015 of an inch. Excessive head space in any center fire firearms starts at about .007-.008 thousandths. The CIP, from what I'v just read is cut to give slightly less head space. In a target gun, that would be the way to go. in a SHTF hi cap weapon that may have to eat a varied diet of may be not so desirably clean ammo, the slightly bigger headspace gap would be preferable.  But again, that's really needle dicking the subject. Good luck on the build.

Thanks. That's about what I've been reading as well. I'll just get the ones that are the right price and fastest shipping.
