Pa10 barrel swap

[CaptFacePwn]

I keep getting different answers on what I would need to do to swap the factory barrel with a different one. I currently have an 18 inch barrel on it. Let's say I want to put a 20 inch barrel.. What needs to be done? I keep hearing that the bolt needs to be bought from the same company, I've heard it's fine to just change the barrel, it's all very confusing!

So if the headspace is off, could it be corrected with the existing bolt or would another one have to be purchased?

Best practice is to buy and sell bolts and barrels together. Correct headspace is pretty much guaranteed that way. 

Headspace doesn't correct easily on this platform because of timing issues with the receiver pin and gas port.

I removed my 18" factory PSA and installed a Faxon 16" pencil. I had the PSA bolt checked with the Faxon by a local gunsmith and it was GTG. No defects noted.

FYI, i had a helluva time removing the barrel nut. If you do too, freeze it. Put the whole assembly into the freezer overnight, then try to remove the barrel nut. Worked like a charm.

Yeah I plan on going to a 20 inch barrel and I just wanna be sure there won't be issues. I appreciate the help!
