Requesting Weapon Mods (Decoration only)

Hello, i'm doing a roleplay as a mafia boss and I just bought my first shop.

I want to sell weapons and other ilegal stuff, or even a legal guns shop (ammu-nation feelings)

I know TS3 have a lot of weapons mods, but I don't know if they are compatible with TS4.

Could someone convert some weapons so I can build my gun shop?

Thanks in advance, and if it is not possible, i'll understand.

(Pardon my english, I'm brazilian)
