Three guns I just made... they're all sort of futuristic, and I went for aesthetics over realism, as you'll most definetly see. Still, I'd like some feedback on them.
'Trident' .50cal Battle Rifle
I wanted to make a multi-barreled weapon, and this is what I eventually came up with. It's supposed to be a semi-auto, anti-materiel rifle with an option to fire one barrel at a time, alternating between the three separate barrels, or go crazy with all three barrels at once.
'Parade Rain' Grenade Rifle
Semi-automatic, long range grenade rifle. The lights on the grip changes color depending on the grenade type loaded into the gun; practice grenades in this case. Basically a smaller version of a grenade launcher, and probably easier to handle (less recoil due to smaller grenades, plus foregrip).
'Rhino Stampede' 9x19mm Gatling Assault Rifle
This one is pretty much my entry into the Impracticality Contest. It's a MASSIVE gun that, even with the low-caliber ammunition it uses, would probably never be useable in real life. Still, it looks cool. The idea behind the huge magazine is that the well extends slightly into the foregrip, and that it's built in such a way that bullets are fed upwards into the reciever from the back of the magazine, with bullets in the front of the magazine being fed down and back as it fires, if that makes sense. Due to its size, it can also hold quite a lot of bullets (as seen by the example outside the magazine).
