As a real-life shooter, I have to ask....where the hell do you put the mag....er clip? Regular mags are (mostly) straight and can easily fit on a belt, in a pocket, in a pouch attached just about anywhere. This one, looks like it would take up way too much space on one's person or be very difficult to quickly remove from a mag-pouch. Not to mention that straight mags are more egronomically sound for rapid release and replacement. Just my humble opinion, but this looks way too awkward.
Granted SR is a RPG and I know that sometimes cool wins out over function. But me personally, I still like my weapons to make SOME sense.
But as a gamer, I always say "If you're having fun with it, run with it!"
