Go/No-Go Headspace Gauges for 300 AAC Blackout

[Trinimon]

Hi folks, anyone got a set of Go/No-Go headspace gauges for the 300 Blackout to lend me for a week or two if you're not in a rush to use it? I'll gladly pay for shipping.

I'm building a 300BLK upper and should have all my parts within the next week, just waiting for CFO to approve my matched upper/lower. I looked online at Brownells but they're back ordered on these.

Thanks if you can.

Do a net search for headspace guages. There are several sites, Stateside, that rent 'em and send 'em across the border wirth no fuss.

Thanks Sunray. I'll give that a look see.

Wouldn't a 223 gauge work?

do a wiki search. The shoulder on the blackout appears to be WAY lower than the 223

Here's why.
