Can i transfer my gta v weapons to gta online?

Grand Theft Auto Online is a separate online multiplayer component of Grand Theft Auto V, and it maintains its own inventory system. Weapons owned in the single‑player story mode are not carried over to the online game. Players can purchase or acquire weapons within GTA Online independently; any items earned in GTA Online remain in that realm only. No developer documentation or in‑game mechanic exists that allows transferring weapons between the two modes.
