How do i get the insurgent on GTA V?

In GTA V, you can obtain the Insurgent by purchasing it from the Warstock Cache & Carry website after completing the mission "The Merryweather Heist." Alternatively, you can find it during certain missions or in the game world, particularly in areas where Merryweather security is present. In GTA Online, you can also steal one from NPCs or use it in heist setups.
