U4GM Guide to GTA 5 Bunker Sales and Research

Andrew736

Gunrunning is the standout money-maker during the third week of the Business Rivalries Event, running from September 17 through September 23, 2026. Solo players can build a strong cash balance without relying on a crew, especially if they already understand how to manage a bunker. The quickest early target is the Weekly Challenge: finish three Bunker Research Missions and you will receive $1,000,000 plus the Camo Ammu-Nation Sweatsuit. Players checking GTA 5 Accounts should still focus on this in-game reward first, since the missions also provide double cash, reputation, and research progress.

Claim the Grapeseed Bunker While It Is Free

If you do not own a bunker, head to Maze Bank Foreclosures through your phone and claim the Grapeseed location before September 23. It normally costs $1,750,000, so this offer saves a serious amount of starting capital. Once you arrive, use the laptop and complete the setup job. The Personal Quarters upgrade is worth considering for $159,000 because it lets you spawn at the facility. Skip the shooting range and other extras for now. They can wait until your business is already paying for itself.

Complete Research Missions First

Register as a VIP, CEO, or Motorcycle Club President, then call Agent 14 and request a Bunker Research Mission. The jobs are simple enough for one player. Travel to the marked area, deal with the targets, collect the research, and return safely. Completing three of them unlocks the large weekly payment. Keep your bunker staff on research while working through the challenge, then switch them to manufacturing once the objective is complete.

Activity	Normal Payment	Event Payment	Solo Notes
Ammu-Nation Contract	$50,000	$100,000	Short delivery with a 15-minute limit
Three Research Missions	Challenge reward varies	$1,000,000 bonus	Also awards the Camo Ammu-Nation Sweatsuit
Los Santos Bunker Sale	Depends on stock	Higher destination value	Best choice when selling alone

Keep Production Moving

Buy supplies for $75,000 rather than stealing them. It costs money upfront, but the time saved is far more useful during a bonus week. Equipment and Staff upgrades should be your main investments because they improve production speed and stock value. Security is helpful too, particularly if you leave the game running for long periods. While stock builds, watch for the Duneloader inside the bunker. Delivering its weapon parts to Ammu-Nation now pays $100,000 and usually takes only a few minutes.

Sell With a Solo Plan

When the stock is ready, choose Los Santos for the better payout. Phantom Wedge deliveries are usually the least stressful option because the truck can push through traffic. If you receive a sale involving several vehicles, leave the session and try again in an invite-only lobby; a small amount of stock may disappear, but the reset can save a lot of frustration. With a free bunker, the weekly challenge, and regular Ammu-Nation work, even players comparing buy cheap GTA 5 Accounts options can see why this event is such a useful starting point.
