Yes it is a Rosarms baby. Here is a photo of a Rosarms you probably have not seen before. It has the exact same style of blade as the C7 bayonet I got today. I am falling in love with the shiny and am even polishing my INFI.
I know what you mean, I'm about to add one to my collection...me like shiney too. I was thinking of the fox-1, but there they have a few designs that I like.
