Allow me to introduce, the SMG! Concept by alex_bo:
The SMG is the human team's most basic weapon. It is issued to every clone trooper for free and is potentially the most frequently used gun in the universe. The leitmotif of its construction is the simplicity and reliability of an established 21st century design, delaying the upcoming era of laser weapons by centuries.
Since this concept surpasses all design requirements, modelers are kindly asked to stick close to it. If you have experience with guns and are interested in bringing this masterpiece to life, post here!
