How to make custom weapons in GTA 6

Can you make your own custom weapon in GTA 6?

Not that Rockstar has announced. We found no weapon designer, crafting system or way to build a gun from parts on its GTA VI and editions pages. What it has named is a pattern you can put on most guns, and a few personalized guns that come with the Ultimate Edition. Those are set items, not a design tool.

Rockstar hasn’t published a full weapon list either, as our weapon count answer explains.

What weapon customization has Rockstar named?

The Vintage Vice City Pack, the pre-order bonus, includes what Rockstar’s editions page calls “an iconic weapon pattern that echoes the excess of the past”. Its GTA VI page says you can put the tropical design on “most guns”, and that it is inspired by Tommy Vercetti’s palm tree shirt. One Rockstar image is described as Jason holding a submachine gun covered in the pattern. Our pattern page has the detail.

The Ultimate Edition adds personalized guns. Rockstar lists sidearms with detailed engravings, Jason’s Girardi ES9 and Lucia’s Klose K17, and GamesRadar+ reports that the ES9’s engraving reads “Sua Sponte”. It also lists the Hawk & Little Morgan revolvers, a matching pair for Jason and Lucia with etched grips, engraving and what Rockstar calls a “high-performance scope”. Rockstar doesn’t say which guns the pattern leaves out.

Are there attachments, upgrades or skins?

Rockstar hasn’t described a system for them. The one part it names is the scope on those Ultimate Edition revolvers, and GamesRadar+ spotted a red dot sight on Jason’s submachine gun in Trailer 2. A part on a set weapon doesn’t tell us whether players can add or remove it. We found no suppressors, magazines or damage upgrades on Rockstar’s GTA VI and editions pages when we read them on November 14, 2026.

As for skins, the only finish Rockstar names is the Vintage Vice City pattern, and we won’t add others from rumor. The pattern, the engraved pistols and the scoped revolvers show that some guns have visual variants. They don’t describe a system.

How did GTA V and GTA Online do it?

In GTA V (2013), Grand Theft Wiki says Ammu-Nation let players fit weapon modifications such as suppressors, extended magazines, grips, scopes and color tints.

GTA Online later added Mk II weapons with the Gunrunning update on June 13, 2017. GTABase’s report of that update says the Mk II upgrades were available from the Weapon Workshop of a Mobile Operations Center. That is history, not a promise for GTA 6.

What is still unknown?

We don’t know whether Ammu-Nation or any other shop sells weapon mods in GTA 6, which guns the pattern leaves out, whether Standard Edition players get any customization beyond the pre-order pattern, or what any of it costs. The site’s weapons section tracks what Rockstar and outlets have named, with each entry labeled by certainty.

What we will test after launch

We will check whether weapons can be modified at all, where any attachments are bought, which guns accept the pattern, and whether upgrades change how a weapon handles. Real steps will replace this page once we have done it.
