Chamber Question

[Greyfox]

The vender has returned my email and will fix the problem. I did get a no-go gauge from PTG. To use it correctly, I remove the extractor claw from the bolt? Anything else?

A headspace gauge is a precision made tool. To prevent damage to your no-go gauge need to remove both the ejecter and extracter. To properly headspace there has to be no resistance when useing the guage.The ejecter has alot of force against the gauge and could damage it when you try to slam the bolt into it under spring tension. That is one tough spring to overcome.

Clean the chamber first. Check the bolt face and clean if needed.Then clean the no-go gauge.
Now insert the no-go gauge into the chamber.
Slide the carrier/bolt into the rifle untill you feel resistance,then stop pushing.
Now check the back of your upper receiver and see if the carrier is even with it. A no-go gauge will have the carrier sticking out the back of the receiver a small amount. If the carrier is even then you have excesive headspace.

A go-gauge will have the carrier close flush with the back of the receiver.A no-go guage will have the carrier sticking out the back.

You made a wise choice to purchase the headspace gauge.
