BUNKER GUIDE — GUNRUNNING, RESEARCH & STEADY MONEY

Why Bunker Still Matters

The Bunker is the oldest business that remains genuinely worth running in 2026. Launched in 2017 with the Gunrunning update, it does two things no other business does: it produces weapon stock (the highest-paying Nightclub product at $20K/unit) and it unlocks MK II weapon upgrades that are otherwise inaccessible. Even players who don't actively grind Bunker sales own one for the MK II infrastructure.

The Bunker is also the most "set and forget" of the active businesses. Once supplied, it runs in the background while you do anything else. Unlike the Acid Lab, which produces faster and requires more frequent attention, the Bunker is happy to be ignored for hours. This makes it ideal for veteran players who run multiple businesses in parallel.

Compared to the Acid Lab, the Bunker is slower per hour and has more annoying sale missions. Compared to the Nightclub, it requires more active management. Its niche is the "steady reliable income with MK II benefits" middle ground.

Best Bunker Location

Bunker location matters more than for most businesses because the sale missions are point-to-point delivery runs across the map. A bad location means longer sale routes and higher risk of failure.

Bunker locations ranked (best to worst for sales):

• Chumash: $1.65M. Best overall. Closest to Los Santos, shortest sale routes, easy highway access. Recommended.
• Farmhouse: $1.165M. Cheapest. Central location, reasonable sale routes. Best budget option.
• Paleto Forest: $1.65M. Northern, scenic. Slightly longer sale routes but no significant downsides.
• Smoke Tree Road: $1.85M. Far east. Longer sale routes but quieter — less griefer activity.
• Grapeseed: $1.95M. North-central. Average performance.
• Lago Zancudo: $1.65M. Avoid. Inside Fort Zancudo military zone — NPCs aggressive on most sales.
• Raton Canyon: $2.095M. Far northwest. Avoid. Terrible sale routes, longest distances.
• Other locations: Generally avoid anything outside the recommended list. The price/route ratio is bad.

If you don't care about budget: Chumash. If you do: Farmhouse. Don't overthink it.

Essential Upgrades

The Bunker has three upgrades. Two are mandatory, one is optional.

• Equipment Upgrade: $1,155,000. Doubles production speed. Mandatory.
• Staff Upgrade: $598,500. Faster research and production. Mandatory if you're doing research.
• Security Upgrade: $345,000. Reduces NPC attacks during sale missions. Recommended.

Total recommended buy-in: ~$3.25M for Chumash + all three upgrades. Don't cheap out on the Equipment Upgrade — without it, the Bunker produces at half speed and is genuinely not worth running.

Buy vs. Steal Supplies

The Bunker has the most debated buy-vs-steal calculation in the game.

Buy supplies: $75,000 for a full supply bar. Instant. Produces $315K-$420K in stock (full bar with Equipment Upgrade), depending on assignment.

Steal supplies: Free. Each Steal Supplies mission gives ~25% of a supply bar. Four missions = full bar = $315K-$420K in stock. Each mission takes 5-10 minutes.

Net math:

• Buy supplies → $315K-$420K profit per 2.5 hours of production. Time spent buying: 30 seconds.
• Steal supplies → $315K-$420K profit per 2.5 hours of production PLUS 30-40 minutes of mission time before that.

The verdict: Buy supplies. Always. The only reason to steal is if you literally have no other activity to do and want free progression. For any player with even a basic empire, the 30 minutes saved per cycle is worth dramatically more than the $75K saved.

MK II Weapon Research

The Bunker's killer feature beyond money is research. Your Bunker staff can either produce stock OR conduct research at any given time — you choose which via the interaction menu.

Research unlocks MK II versions of weapons (more damage, customizable ammo types) and various vehicle weaponry. The full research tree contains 40+ items. Random selection cycles through them; each completed research takes 3-4 hours of game time without upgrades, 1.5-2 hours with the Staff Upgrade.

Pay to skip research: $225K per item via the interaction menu. Worth it for the most valuable items (Heavy Sniper MK II, Special Carbine MK II, Pistol MK II) and any vehicle MK II weapons. Not worth it for the cosmetic-only items.

Strategy: Start with research mode immediately after buying the Bunker. While supplies are running, the Bunker is researching. After 40+ in-game hours, you'll have most of the meaningful MK II weapons unlocked. Then flip to permanent production mode.

Sale Missions & Solo Strategy

Bunker sale missions are the most variable of any business. The vehicles assigned depend on stock value:

• Single-vehicle sale (low stock): Drive one Insurgent, Marshall, or Phantom Wedge. Solo-friendly.
• Three-vehicle sale (medium stock): Drive three Dune FAVs, Half-tracks, or Phantom Wedges. Requires three trips solo (no crew = drive one, return, drive next).
• Maximum stock single-vehicle: If you sell at exactly 20% stock or in certain other configurations, the game gives a single high-value vehicle. This is the solo meta.

The 20% sale trick: Wait until your stock is exactly 20-25% full (one segment), then sell. The game assigns a single vehicle for the smaller cargo. You get ~$168K solo without the public bonus. Repeat this 5x across a few hours and you've sold what a full Bunker sale would have, with much less risk.

Public lobby bonus: +50% high-demand bonus in populated public sessions. A $168K solo sale becomes $252K. The risk is real — three-vehicle sales in public are griefer central. Single-vehicle 20% sales are the only reliable public-lobby option.

The Nightclub Connection

The Bunker's most important long-term value is as a Nightclub feeder. Once you link the Bunker to your Nightclub, the Nightclub generates Sporting Goods (the highest-paying Nightclub product at $20K/unit) independently of whether you're actively running the Bunker.

This means a mature GTA Online empire has the Bunker doing TWO things simultaneously: producing its own stock for direct sales, and feeding the Nightclub passively. Both income streams happen in parallel.

Recommended progression:

1. Start with the Acid Lab (cheap, fast, easy)
2. Buy Kosatka and start running Cayo Perico
3. Buy Bunker for research and MK II weapons
4. Buy MC clubhouse + Cocaine Lockup + Meth Lab
5. Buy Special Cargo Warehouse
6. Buy Nightclub and link all of the above

The Bunker fits neatly in the middle of this empire — it pays for itself, it unlocks MK II weapons, and it feeds the Nightclub. Few players who own all the major businesses ever sell their Bunker.
