Help with modding

Ok so ive eeen trying to transform the default gun into an aug-a3 se and ive been sucessfull at changing the textures, the 3d model in the shop, the textures in the shop, and the name while playing a game. The only problem is i cant figure out how to change the 3d model of it while playing in a game.

I was using the hex editor for this.
