Becoming a weapons dealer in GTA 5 Online primarily involves owning and operating the Gunrunning business, introduced with the Gunrunning DLC. This business centers around manufacturing and selling illegal arms from an underground bunker, offering both active missions and passive income streams GTA 5 Accounts.

Starting Your Weapons Dealer Business
To become a weapons dealer, you first need to purchase a bunker property, which costs around $1.5 million. After buying the bunker, you must complete a simple setup mission to get your business operational. This mission involves delivering supplies and is straightforward, unlocking your ability to manage the bunker’s manufacturing and research functions.

How the Gunrunning Business Works
The core gameplay loop involves acquiring supplies (either buying or stealing), manufacturing weapons, and then selling the produced stock. The bunker produces units of weapons over time, which you can sell in bulk through delivery missions. These missions often involve transporting your product in vehicles while defending against waves of enemies, including heavily armed mercenaries.

Selling and Profits
Selling your product involves missions where you deliver weapons in one to four vehicles, depending on how much stock you sell (each vehicle carries 25 units). Selling in Los Santos yields higher payouts compared to Blaine County, with fully upgraded sales netting up to $1,048,000 for 100 units. However, these missions can be challenging, especially solo, due to enemy attacks on your delivery vehicles and timers that prevent splitting deliveries.

Arms Trafficking Missions
In addition to bunker operations, you can engage in Arms Trafficking missions by owning the Mackenzie Field Hangar ($1.475 million). These missions are quick, varied tasks involving stealing or delivering weapons and can pay up to $660,000 per mission, making them excellent for active, high-reward gameplay. Missions include delivering weapons, stealing cargo, and flying special aircraft, often completed in under five minutes.

Tips for Success
1. Steal supplies to maximize profit margins GTA 5 Enhanced Accounts buy.
2. Balance manufacturing and research to unlock powerful weapon upgrades.
3. Use fast, well-armed vehicles like the Oppressor or Hydra to complete missions efficiently.
4. Consider combining Gunrunning with other money-making activities like crate runs or vehicle import/export for higher overall income.
