Now that I'm almost 21, I gave it a try again and somehow managed to make something decent.
Ladies and gentlemen, I hereby present my first attempt at one of my most loved weapons, the HPVC.

Special thanks to Jorzi for giving me tips so far. Mind that this is still a work in progress and might not be representative of the final product.
As for the polycount, original hipoly model was at 2400ish tris, this one is down to 345 after a LOT of optimization.
Edit:
Improved the model (I still have the WZ-like model though) and made space for the gun mantlet thingie then added a bore evacuator

I tried to get the polycount as low as possible, even though it's already as low as 359, but Blender is "Working as intended" according to this so I couldn't reduce it any further.
Edit #2:
After another lot of optimization (again, thanks to Jorzi) the model is at 250 tris
