40mm Grenade Launcher WIP 1

Ok, so this one is a little less "out there" than my recent works, but whatever. The idea with this one is to take your basic automatic 40m grenade launcher, increase the muzzle velocity and barrel length, and then stick two together on a turret. The result is a gun that can lob grenades at least two miles away at a sustained rate of 80 rounds per minute. This is the weapon that I plan to mount on the top of my DTT tank. I will probably end up modifying it some, hence the WIP.

p.s. now all thats left for me to do is to build the chassis of the tank and mount these weapons!

Just discovered skylight! Going back and re-rendering my recent submissions employing said discovery.
