Free Railgun in GTA 5: The Ammu-Nation Shooting Range Trick

Yes, you can put a Railgun in your inventory in GTA 5 story mode without spending a single dollar, but two conditions have to be true first: you need to be a "returning player" whose save carried over from the PS3 or Xbox 360 era, and you need to be willing to use a shooting range trick instead of the normal purchase. This guide explains what the Railgun actually is, why most players can never unlock it at all, and the exact steps for the free Ammu-Nation shooting range method, plus what to do if none of that applies to your account.

Essentials

• In-game name: Railgun, called "Fusil a impulsion" in the French version, a Heavy Weapon added to GTA 5 in the November 18, 2014 update.
• Eligibility: only "returning players" (accounts that transferred a save from PS3 or Xbox 360 to PS4 or Xbox One, later carried into the PS5/Xbox Series upgrade) can ever unlock it in story mode.
• Standard price: $250,000 at any Ammu-Nation, unlocked after finishing the story mission "Minor Turbulence".
• Free legit route: scuba dive to the wrecked plane at the Alamo Sea after finishing "Minor Turbulence".
• Free shortcut: the Ammu-Nation shooting range "Bonus" challenge lets an eligible returning player pick up the Railgun before the mission is even done.
• Not obtainable at all, on any platform, for players who never owned GTA 5 on PS3 or Xbox 360.

What Is the Railgun in GTA 5?

The Railgun is a one-shot, one-kill Heavy Weapon that fires an electromagnetic slug capable of punching through almost any vehicle armor in the game. Rockstar added it in a post-launch update rather than at release, which is why it never shows up in the default weapon wheel and most players go their entire playthrough without ever seeing it. It deals enough damage to total most cars and helicopters in a single hit, which is exactly why Rockstar gated it behind a specific unlock condition instead of selling it to everyone from day one.

If you have looked into GTA 5's other rare unlocks, this scarcity pattern is familiar: some of the game's most powerful tools are locked behind conditions most players never trigger, the same logic Rockstar used for several rare vehicles hidden around the map.

Who Can Actually Unlock the Railgun in Story Mode?

This is the part that trips up most people searching for this trick: the Railgun in story mode is only available to "returning players". That specific Rockstar label means an account that owned and played GTA 5 on PS3 or Xbox 360 and later transferred that save file to PS4 or Xbox One when the current-gen version launched in November 2014. Players who transferred their save further into the PS5 or Xbox Series upgrade keep that returning-player status too.

If your first copy of GTA 5 was on PS4, Xbox One, PC, PS5 or Xbox Series X|S, with no PS3 or Xbox 360 save ever attached to your account, the game does not grant returning-player status, and there is no legitimate in-game method to unlock the Railgun in story mode. That includes PC: since the platform was never part of the original PS3/Xbox 360-to-current-gen transfer program, PC accounts do not carry the flag. Cheat codes will not spawn it either, since it is not tied to any of the GTA 5 weapon cheat codes.

The Standard Way: Minor Turbulence and Ammu-Nation

For eligible returning players, the intended path is straightforward. Complete the story mission "Minor Turbulence", part of Trevor's late-game missions, and the Railgun becomes purchasable at any Ammu-Nation store for $250,000. That is a steep price even by late-game GTA 5 standards, which is why so many players look for a way around it.

The Free Way: Diving for the Wrecked Plane at the Alamo Sea

There is a completely legitimate free alternative that does not require any exploit, just a bit of exploration. After finishing "Minor Turbulence", head to the Alamo Sea, the lake where the mission's plane crash takes place, put on scuba gear, and dive down to the wreckage. The Railgun is sitting inside the cockpit section of the sunken plane, free to pick up. This method still requires returning-player status and still requires finishing the mission first, but it skips the $250,000 price tag entirely.

The Ammu-Nation Shooting Range Trick, Step by Step

This is the method most people mean when they search for a "free Railgun trick": getting it before ever completing "Minor Turbulence" or paying anything, using the shooting range's Bonus Challenge.

1. Go to either shooting range Ammu-Nation location, in Pillbox Hill or Cypress Flats.
2. Talk to the range attendant and select the "Bonus" challenge option, rather than one of the regular weapon-category challenges.
3. Choose the bonus challenge that uses the Railgun as its weapon. This challenge type is only offered to accounts with returning-player status, which is the same eligibility gate as everything else on this list.
4. Once you are inside the challenge holding the Railgun, aim it at your own feet and fire.
5. The shot kills your character instantly and ends the challenge, but instead of taking the weapon back as it normally would, the game respawns you outside the shooting range still carrying the Railgun in your inventory.

From that point the Railgun behaves like any other weapon you own: it stays in your inventory across saves, can be carried between all three protagonists, and can be restocked with ammunition at any Ammu-Nation once you have it.

Does the Trick Work on PC, PS5 or Xbox Series X|S?

The Bonus Challenge itself only appears for accounts flagged as returning players, regardless of which physical console you are currently playing on. If your save carried the flag from PS3 or Xbox 360 through to PS4 or Xbox One and then into the free PS5 or Xbox Series upgrade, the challenge and the trick both still work there. If your account never had that flag, the Bonus Challenge for the Railgun simply will not appear in the shooting range menu on any platform, PC included, and there is no known legitimate workaround.

Is This an Exploit or a Legitimate Trick?

It sits in a gray area. Nothing about it involves external software, save editors, mods or online services, it is a sequence of normal in-game actions inside a menu Rockstar left in the game. That said, it does bypass the intended unlock sequence (finish the mission, then pay), so treat it as a known quirk rather than an officially documented feature. It has no bearing on GTA Online and carries no ban risk, since it only touches single-player systems.

Railgun in GTA Online: A Different Weapon Entirely

Do not confuse this with GTA Online. The multiplayer Railgun is a completely separate unlock with its own price and its own vendor, the Gun Van, and none of the returning-player restrictions or shooting range tricks from story mode apply there. If you are looking for money-making methods to afford weapons like this in Online, a ranked list of the fastest GTA Online money methods is a better starting point than trying to port this story mode trick across.

FAQ

Do I need to be a returning player to try this? Yes. Without that flag on your account, the Bonus Challenge for the Railgun does not appear at either shooting range, and the trick cannot be attempted at all.

Can I lose the Railgun after picking it up this way? No. Once it is in your inventory it behaves exactly like a purchased weapon and persists across saves and story progress.

Does finishing "Minor Turbulence" first block the trick? No, but it makes the trick unnecessary, since the Railgun becomes purchasable for $250,000 right after, and the free wrecked-plane dive becomes available too.

Is the Railgun worth the trouble for casual players? For story mode, yes if you enjoy one-shotting armored vehicles and helicopters, though most players are still better served brushing up on which GTA 5 cheat codes still work in 2026 if all they want is quick destruction without the eligibility requirements.
