Can players use story mode weapons in gta online?

Grand Theft Auto Online is described as an online multiplayer component of Grand Theft Auto V, separate from the single-player story experience. The evidence only outlines the game’s release dates, platform availability, and basic gameplay structure—it does not mention any crossover of weapons or other assets between the story mode and the online component. Without explicit information indicating that story mode weapons are available in GTA Online, we cannot affirm that they can be used. Therefore, based on the available verified source, there is no evidence to support the use of story mode weapons in GTA Online.
