A new mod made by an aspiring modder. So far the only thing is a heavy machine gun but I plan on adding more. Any tips would be nice, and I could use help with spriting.

History:
A young intelligent man grew up and looked to the stars. He dreamed of making the galaxy a better place. One day, the Coalition recruited him to design better weapons and armor to help their soldiers. He agreed.

Just tested you mod and I can say you did a pretty good job.
I personally like vanilla balanced guns/actors/mods so I think that you made your gun a little too good. It's very accurate, pretty good damage and 150 clip size. It tops any gun in vanilla, but if you like non-vanilla balanced mods, it's great.
As for spriting, sure it could use some upgrades, but you can try doing it little step by step, firstly messing with the shape, add details and shading. Gun doesn't really need to look like something modern, so go crazy with it.

Yeah I have yet to actually get off my bum and change the accuracy.
