Making a new gun mod

I'm making a NEW gun mod, anybody can help, and the old mod has been SCRAPPED, it has been deleted because the update for MCreator did it, I think... So... anybody that wants to be a modeler with Blockbench or something, OKAY! also, any moderator or Klemen, bring back my old mod if you can, okay? it hasn't been published so I think you can't.
