Gunrunning is the main attraction during the third week of the Business Rivalries Event, running from September 17 through September 23, 2026. For solo players, it is a good time to build a steady income stream without relying on a crew. The free Grapeseed Bunker gives new owners a useful starting point, while experienced players can use the event bonuses to push their earnings past two million dollars. Players looking to expand their character options can also compare GTA 5 Accounts before deciding how they want to approach the week.

Start With the Free Property

Open the in-game phone, visit Maze Bank Foreclosures, and claim the Grapeseed Bunker before September 23. It normally costs 1,750,000 dollars, so this offer saves a large amount of cash. The Personal Quarters upgrade is worth considering for 159,000 dollars because it lets you spawn at the Bunker. That small convenience adds up quickly when you are moving between sales, research jobs, and supply runs. Skip the shooting range and other optional additions until the business is making money.

Set Up the Business Properly

After buying the property, travel there and complete the short setup mission. Then use the laptop to open Disruption Logistics and purchase the Equipment and Staff upgrades when your budget allows. They improve production speed and help each supply purchase produce more stock. The Security upgrade is useful too, especially if you plan to leave the business running for long periods. Keep your staff on Manufacturing unless you specifically need research progress.

Use the Event Bonuses

Ammu-Nation Contracts are easy to fit between other activities. When the Duneloader appears inside the Bunker, deliver the weapon parts to the marked Ammu-Nation store. The usual reward is 50,000 dollars, but the current bonus raises it to 100,000 dollars. You get fifteen minutes, which is normally plenty of time. Bunker Research Missions also pay double cash, reputation points, and research progress. Completing three of them unlocks the weekly reward, including a 1,000,000-dollar payment and the Camo Ammu-Nation Sweatsuit.

Keep Sales Simple

Buy supplies for 75,000 dollars instead of stealing them. It saves time and lets you handle other work while stock builds in the background. When the product is ready, choose the Los Santos sale for the higher payout. Solo owners should aim for a manageable delivery, especially a Phantom Wedge job. Before starting, use this quick routine.

Buy supplies and confirm that staff are assigned to Manufacturing.
Complete any available Ammu-Nation Contract.
Run Research Missions until the weekly challenge is complete.
Sell to Los Santos when the stock value justifies the trip.

Some sale missions are awkward with one player, so do not force a delivery that clearly needs several drivers. Leave the session and try again from an invite-only lobby, accepting the small stock loss when necessary. With regular supply purchases and the weekly rewards combined, the Bunker can become one of the most practical solo businesses in GTA Online, especially when paired with cheap GTA 5 Accounts for players starting with limited progress.

Building a Bunker business solo takes patience, from buying supplies to completing research missions and weekly challenges. U4GM offers GTA 5 accounts and responsive support, helping players spend less time starting over and more time on Gunrunning, Ammu-Nation deliveries, and Los Santos sales.
