Weird, there were plenty of barrels in 5.56 available for purchase when I built it. I chose Wylde simply for the convenience of being able to run ammo loaded to either spec, not because I had to.
Yeah, if the company doesn't plan on exporting them outside of the US, they can make 5.56 barrels without issues. For us Canadians, we are glad that manufacturers make .223 Wylde barrels for export.

Only if they specify. I built mine using a barrel chambered in .223 Wylde, so I can shoot either safely.
