Just picked up my PS90 from the recent PSA sale

I want to SBR it, but I had a few questions:

What is the general consensus on having the barrel cut/rethreaded instead of purchasing a separate barrel? Is there a 'go to' place for cutting/rethreading - I have a .308 and .45 suppressor that may support 5.7, so I am concerned about concentricity!

Thanks!
