I spent some time on eBay/Gunbroker searching but not luck. I reached out to Ruger and they said "The barrel is a factory fitted item and can't be sold to anyone; it needs to be installed by our technicians at the factory. We would only re-barrel the firearm with the original length and caliber it came with. "
Is there another forum here I could post on?
I'll sell you an unfired 6 CM barrel. My gun should be here early next week ?
