If you don't know someone with one, you rent a .223 finish reamer for around $36.00 plus shipping. You'll need a .223 go gauge also. There's plenty of how-to tutorials and videos out there.
The only caveat doesn't pertain to to the chamber. It's the rifling in the barrel. Often, a .222 is intended for shorter, lighter bullets up to 55gr and by virtue of that, they often come with a slower twist than a .223. If you try to shoot longer, heavier bullets that a fast twist .223 barrel does well with, they may not stabilize adequately. It's not unusual to find .222 barrels with a 1:14 twist. That's too slow for the longer, heavier bullets. IE, if you intend to shoot surplus XM855 ammo, they may not stabilize as well as XM193.
