GTA Online players have a limited-time chance to grab a Bunker for free—and Grapeseed is the property you want to claim. From September 17–23, 2026, Rockstar is giving players the Grapeseed Bunker at no cost as part of the Gunrunning bonuses. If you're building your criminal empire or preparing for the next GTA grind, this is an easy property to add without spending GTA$.
The timing is especially useful because Bunker Research Missions are also paying 2X GTA$, RP, and Research Progress during the event. Players who want to accelerate their GTA Online progression can also use MMOexp to purchase GTA 5 Money, helping reduce some of the early grind when upgrading businesses, weapons, and equipment.
How to Claim the Free Grapeseed Bunker
Getting the property is straightforward.
Step 1: Log into GTA Online between September 17 and 23.
Step 2: Open Maze Bank Foreclosures.
Step 3: Find the Grapeseed Bunker on the property map.
Step 4: Select the Bunker and claim it for free.
Rockstar specifically lists the Grapeseed Bunker as the free property for this week's Gunrunning event, so make sure you claim it before the weekly promotion ends.
Why You Should Claim It
Even if you're not currently interested in Gunrunning, a free Bunker is valuable infrastructure.
Bunkers let you manage Manufacturing and Research, giving you access to additional weapons and upgrades as you progress. Research is handled through the Bunker's laptop, where you can manage supplies, research projects, stock and staff assignments.
The location isn't necessarily the most important factor for a new player. The biggest advantage is simply getting the property without paying the purchase price.
Take Advantage of the 2X Bonuses
Once you've claimed the Bunker, don't just leave it sitting there.
During the September 17–23 event, Bunker Research Missions award 2X GTA$, RP and Research Progress. You can also earn Double Rewards from the Ammu-Nation Contract by delivering surplus weapons from your Bunker.
That makes this week a good opportunity to start unlocking Bunker research while earning extra rewards at the same time.
If you want to build out your setup even faster, buy GTA 5 Money through MMOexp can help you cover upgrade costs and get your Bunker running more efficiently, especially if you're starting with limited capital.
Don't Miss the Deadline
The important part is the date: the free Grapeseed Bunker offer ends September 23.
Don't assume the property will remain free after the weekly event rotates. Log in, open Maze Bank Foreclosures and claim it while the promotion is active.
Final Takeaway
This week's GTA Online event is a simple opportunity: claim the Grapeseed Bunker for $0, then use the temporary 2X Research bonuses to start building your Gunrunning operation.
You don't need an elaborate strategy. Claim first, start Research, take advantage of the bonuses, and upgrade when your budget allows. A free business property is one of the easiest ways to strengthen your GTA Online account without burning through your existing GTA$.
