.223 NO-GO headspace gauge
« on: August 06, 2007, 06:24:59 PM »

Does anyone have a .223 NO-GO headspace gauge? If so, what are the dimensions of the gauge as stamped on the side?

I have a Forster that is stamped 1.4666, I have a page from ar15barrels.com that lists SAAMI specs for a NO-GO as 1.470. Thats 3.4 thousandths difference. Which is a lot when it comes to chamber dimensions being safe and chamber dimensions being unsafe.

Just curious as to what other gauges might say. As far as I know, Clymer is the only other manufacture that is commonly available.

Jim I have a Military 5.56 "FIELD" gage.  The specs on it are 1.4730 if that helps any?

Thanks to both of you. I ended up buying a No-Go gauge.
