I made these a long time ago but there were some glitches and stuff with them so I didn't release them then, only got reminded that I didn't recently so I fixed them up and here we are.
This has the arms for all of the default HL2 weapons, including the gmod toolgun, but for some reason gmod refuses to load the toolgun model and only uses the old HEV arms one.
Feel free to use these for any custom weapon viewmodels you want, you don't need to ask my permission, though crediting me would be nice.
