Prefit barrel install. No Go / Go gauge was checked.

Installing a Patriot Valley prefit in 7 Creedmoor onto a Zermat Origin.
This girl had very bad, tooling marks, and was very filthy with some sort of film in it. I just installed the barrel in this video to see if the threads all lined up and then took the barrel back off and lapped the barrel then reinstalled it and I use the go/No go gauges.

as soon as you touched the anti-seize I knew it was over. That stuff goes everywhere.

Yup, as usual, all the "experts" got to chime in.

This looks like the contract barrel overrun sale blanks we had. The ones which we said specifically were leftover from a contract and were not our blanks and they were unlapped button barrels.

You don't need the anti-seize. Also, you need to verify the headspacing before removing it from the vice. It's unsafe to "just assume" its right.

No need for go / no go gauges?

What is that platform that your SAC barrel vise is mounted on?

[@sandginkable]

Since you added a lubricant your torque is no longer 90 but is reduced to 70% of that or 63 ftlbs

Medium Palma contour?
