You can tell by the metal welding tube, they have another funny name for it. If it doesn't come with anything, you have to look at the port. If it doesn't look like NPT, you got VCR. You know the VCR gauges alone will cost you the same as another normal NPT style regulator?
So I actually agree with Kevmo, you can get yourself a normal regulator and find parts in Home depot. Starting off with a regulator with VCR tubing is pretty hardcore, not to mention the cost of parts if you ever needed to replace something.
You won't even notice the difference, beside the fact that you will have an amazing beautiful regulator.
