Ummmmm, one of us is missing something here. Both VSA's are pictured at the top and the US VSA is the one installed so that the Eclipse reg can be used.
I'm assuming you are going by the look alone. On my personal guns(of which that was to be one) I take Kapp US VSA's, because they are long like the metrics, and turn them down to look just like a metric VSA but with US threads. I like to do this to keep a more original looking LED that can use any reg.
