Daily Deviation Edit: I had a higher rez, newer file that I uploaded when I got the DD. The old one is in my scraps. thanks everyone!

was playing around in zbrush to do some renders. Gun is 90% modeled, mostly tweaks are needed to fix it up.

the gun is a grenade launcher as well. The grenades are housed in inside the outer bullet ring of the clip.
both projectiles are propelled faster when the barrel of the gun is filled with a mixture of hydrogen and oxygen causing the bullet to travel at much faster speed.
the guns stock extends and the internal mechanical workings and timing mechanics are under the main armor flap, gun settings are under the smaller flap.
the gun premise is similar to a Tommy gun, but because of the high accuracy, the stock can be extended and a tactical stand can be slid out to snipe long range.

examples of sniper mode and the inner workings can be found here.
