8.6BLK heads up.

Good company/brand. I have used many others from them but ran into issue with the 8.6BLK/Creedmoor - would not work with a Faxon chambered product. A PTG did (whom Faxon uses). Until the not yet released SAAMI spec is official just a heads up. 02/24

High Quality

On building ANY weapon, you need to ensure that the headspace is correct. If you don't and just "roll the dice", you could be in for a nasty surprise.

It works!

I used this go guage for my 6.5 grendel build and the bolt did seat. Which is a good thing! I tested my rifle and it didn't go boom in the wrong places.

Easy to use and works

I used this no go guage for my 6.5 grendel build and the bolt did not seat. Which is a good thing! I tasted my rifle and it didn't go boom in the wrong places.

Love ejector cutout

Ive used Clymer, Forster, and some PTG headspace gauges over the years and these were the first ones to come a cutout for the ejector and hole for the firing pin. Makes it so much easier to quickly check headspace without having to strip the bolt. Quality seems very good.

Love the ejector cut

Great Buy

The best feature of this gauge is not having to disassemble the bolt. It worked great verifying an old M1 Carbine I was thinking about buying.
