Hey,
I don't have a SUB rifle but I came across a neat accessory that people may be interested in. http://store.yahoo.com/cdnn/arsynvergrip.html (used with the picatinny rail) This topic was mentioned briefly on the "other" forum but I thought I would present it here. I think its a reasonable price and would look pretty trick. Let me know what you think.

A lot of people like them and there are a wide variety out that will fit. I, personally, can think of better uses for the rail.
