Anyone know the SWEP for Aiming/Shooting?

Hey. I made another post called Aiming/Shooting but since I know it is a SWEP. I don’t know what one. Usually in gMod the aiming and shooting sucks badly but in servers they add something new and better. I think this is it: http://www.garrysmod.org/downloads/?a=view&id=129926
Don’t really trust it unless you guys know a Steam Workshop one. Thanks

Yea. I can’t download that one btw. It is missing a download. Anyone know a steam workshop one? please
