Pa10 barrel swap


Recommended Posts

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.
