After barrel expands again it will be solidly married especially if you use proper bounding agent.
Try only barrel not slide. Liquid Nitrogen is your best friend.

I have been trying to figure out how this would affect the installation. Seems like freezing the barrel would actually defeat the purpose, as it will reduce the distance from the shoulder to the thread, and it may also affect the pitch of the screw. I know that freezing works great on press fitted parts, but I'm still not sure how it would work on threaded parts. Have you tried this method?

Hi Rick, great tutorial! I've not used the anti-seize, but will start... I'm thinking about making a hardened receiver thread fixture, and a hardened barrel thread, with the class fit you mentioned... just for a benchmark when checking out parts for compatibility... ,... again, great thread! best to you Rick, til...lat'r....GT
