Looks like two rapidfire mods to me? It goes back to what I always said, when it comes to rapidfire, anybody can hit the max speed, so long as they've bothered to spend the time to dial-in the speed to the perfect value to match the in-game cap. I always told customers to buy from any reputable shop. Just no e-bay mods. Those e-bay guys often are running old, stolen code.
I've also always told customers that if all they are interested in is rapidfire, that Viking may not be the best value. If you aren't using all the other modes that Viking offers (Evan is showing a "Standard" 8-mode which is not even speed-programmable), and you just want rapidfire, then you should just look at a mode that's under $100. (Tyr's Hand priced at $99

(This post is with the exception of the macro controller, which has a digital-to-analog converter on the triggers and is able to do more than a traditional rapidfire, and also with exception to COD:WAW which requires a non-50% duty cycle. In this case, if you want THE FASTEST rapidfire then you'd have to buy a macro).
