I don't think it would be too interesting. It's probably cheaper to keep the same tooling from the PPX and use it on the Creed barrels. Remember cost is a big factor for the Creed. Keeping traditional rifling probably helps keep the cost down.
New here and first post. I purchased a Creed a few weeks ago. I haven't had it out to shoot yet because of the three W's (Work, Wife, & Weather). Today I was able to break it down and wipe it down with some CLP and take a look at the insides. The barrel on this gun looks like a standard rifled barrel to me as was expected. I hope I can take it out soon to run some rounds through it.
