Screenshots of what you're doing.

I'm thinking ditch the multi-barrelled design altogether and instead have either a single large muzzle that can spit out a handful of projectiles or maybe instead have a few prongs (maybe like three of them in a Y shape) on the front instead between which the projectiles would originate. Also get the tubes to stick out of the thing a bit (maybe even have them falling out of it a bit clumsily) and maybe make the gun fatter.

EDIT: Another thing I've noticed is that the where the front site sits all the way to where the barrels end does make the gun look freakishly long for what it is in my opinion. As drastic as it sounds, you may want to chop that off. In my mind when I handle the crylink (think of the way it fires, spreads, etc.), I'm handling some scrappy, but hi tech and alien bastardization of a short barrel or sawed off shotgun that's been hobbled together and somehow just works where it's needed.
