Nice. Being abled to delete specific parts makes editing the guns a whole lot easier!
Also, the bullets stopped tunneling but they now go all over the place. Is this because I didn not put on enough barrels (recoil)?
Well yes and no, there was a bug i didn't notice before in terms of accuracy and recoil. Basically you're either accurate, or inaccurate. Nothing in between. So basically, if you added more barrels you should in theory reach the point where it will always be 100% accurate.
I have already fixed this i just haven't published the build yet (I have to disable a feature i was working to do so).
