I'm working on a similar project, with some enhanced features and improvements.
For now, I managed to get the bullet logic working, plus having seperate ammunition for sniper rifles (to fix the range issue).

No, the scope grew too big and it stopped being fun

You can fork the mod and do what you want with it

Is there anyway you could update this mod, just to be compatible with the current version? It would be much appreciated. I am clueless with programming, but I tried the old switch version in the info file, unsuccessfully. The ability to aim and shot the weapon on my own really is a game changer for me. I wish the base game had a way to turn off auto-aim.

I made a partial recreation of the mod, it only does the bullets atm, is that enough for your needs?
