This is a series of guns that I did for the newly released Shadowrun RPG 4th edition supplement book Arsenal [ [link]
]
Since the game is a near future game I tried to keep the basic design elements comparable to modern-day versions of the guns. The guns are as follows:

PPSK-4 Collapsible Machine Pistol
PSK-3 Collapsible Heavy Pistol
++ [ These 2 guns are designed to mechanically fold up into an indistinguishable composite block to be undetectable: stealth weapons ] ++
HK Urban Combat
++ [ This weapon has a a special internal hydraulic recoil compensation system. ] ++
Auto-Assault 16
++ [ The latest version of the brutal, full-auto shotgun ] ++
Ultimax MMG
++ [ A simple, weather resistant modern version of the MMG ] ++
