Nerf GelFire: All 8 Blasters, the Water Soak and the Real Safety Rules

Nerf GelFire is the line that fires water beads instead of foam. No darts, nothing to pick up afterwards, and a completely different set of rules for how and where you play.

It is also rated 14 and up, and the ammunition has to be soaked in water for hours before it works. Both of those catch people out, so they go at the top rather than in the small print.

This page covers all 8 blasters, what a GelFire round actually is, how the line compares with darts and Rival, and who should stay away from it.

What Nerf GelFire is

Nerf GelFire is a sub series of Nerf Pro, launched on 1 November 2022. It was Nerf’s first gel blaster line.

Three things separate it from everything else in the catalogue:

• The ammunition is water. Super absorbent polymer beads that burst on impact
• There is no cleanup. Nothing survives the shot, so nobody crawls under furniture afterwards
• It sits under Nerf Pro. Same shelf as Rival in intent, aimed at teenagers and adults

Unlike Nerf Pro dart blasters, Nerf GelFire is sold internationally, which is why the grey trigger versions further down this page exist at all.

The rounds, and the soak nobody mentions

A GelFire round arrives dehydrated. It is a hard bead about the size of a grain of couscous, and it does nothing at all until it has been soaked.

Refill packs are enormous. Hasbro sells them in packs of 5,000 and 15,000 rounds, because a burst round is gone and a game gets through them fast.

They have to grow first. Add water and wait. This is the single biggest practical difference between a Nerf GelFire blaster and a dart blaster, and it is the reason spontaneous games do not happen with this line.

They burst on impact. That is the appeal. No collecting, no sorting, no arguments about whose darts are whose.

They leave water behind. An afternoon of play leaves a damp patch and small fragments of polymer on the ground.

A glow in the dark round refill exists too, added in 2024, which is a genuinely good idea for a summer evening game.

Every Nerf GelFire blaster

Every Nerf GelFire blaster released, from the community Nerf wiki product record.

A MrBeast branded Mythic also exists, which is the same blaster in different clothes. It counts as a variant rather than a ninth Nerf GelFire model.

Gel rounds against darts and Rival

Choosing between Nerf GelFire and the rest of the catalogue is not really a performance question. It is a question about what happens after the shot.

Darts need no preparation and total cleanup. Every dart is picked up, counted and reused, which is fine indoors and tedious in long grass.

Rival rounds are the same deal in ball form, and they roll further than darts do.

Nerf GelFire rounds need hours of preparation and no cleanup at all. Nothing to find, nothing to lose, nothing to argue about.

If your problem is that half the darts vanish every game, this line solves it completely. If your problem is that nobody has time to prepare, it makes things worse.

The age rating, and why it is 14

Nerf GelFire is rated 14 and up, the same as Rival and Hyper. That is a manufacturer guide rather than a safety certificate, but here it is worth taking seriously.

Standard blasters fire at around 150 FPS, which is well above the speed of a normal Elite dart blaster. Combine that with a hard, small projectile and eye protection stops being a nice idea.

Three rules any group should agree before a first game:

• Eye protection on, all the time. Not just while firing. A round can arrive at any moment, from any direction
• Nothing above the shoulders. The standard rule everywhere, and it matters more at these speeds
• Everybody knows what they are playing with. A bystander who wanders in mid game is the accident waiting to happen

The velocity itself is measurable, and if you want to know what a given speed means in energy terms our kinetic energy calculator does the arithmetic.

Grey trigger versions fire slower

This detail costs people money and it is almost never explained on the box.

Some countries require a grey trigger on toy blasters to comply with local toy law. Nerf GelFire ships those markets a version built to that requirement.

The grey trigger versions fire at around 100 FPS instead of the standard 150. That is a real performance difference, not a cosmetic one.

It matters secondhand and it matters when importing. A blaster bought from a different market can be the slower version, and the trigger colour is the visible tell.

Neither version is faulty. They are built to different rules, and knowing which one you are looking at prevents an unpleasant surprise on the first game.

Where you can actually play

Nerf GelFire is an outdoor game and it is worth being honest about that before buying.

Indoors is a no. Water plus polymer fragments plus carpet is a bad combination, and a burst round on a wooden floor is a slip hazard.

Grass is ideal. The rounds break down and disappear into the ground.

Hard surfaces need a sweep afterwards. Patios and driveways collect the fragments and stay slippery until they dry.

Check the rules where you play. Some public spaces and organised venues treat gel blasters differently from dart blasters, and a few do not allow them at all.

Neighbours are worth a thought as well. Gel rounds are quiet compared with a flywheel blaster, but a fence line takes hits, and a game that sprays a shared boundary is the kind of thing that ends a summer of games early. Play away from the fence and nobody has the conversation.

Local law is worth a search too. A handful of places regulate gel blasters separately from foam dart toys, and that is a check worth doing before buying rather than after.

How to prepare Nerf GelFire rounds properly

Preparation is the part of Nerf GelFire nobody demonstrates in an advert, and doing it badly is the most common complaint about the whole line.

Use plenty of water. The beads absorb far more than looks reasonable, and a bowl that seemed generous ends up drained and half the batch stays hard.

Give it hours, not minutes. Rounds that are still firm in the middle break inside the blaster instead of leaving it.

Do a small test batch first. Water hardness and temperature both change how the beads swell, so learn what your tap water does before you soak thousands.

Drain them before loading. Rounds sitting in water keep swelling, and oversized rounds jam.

Store soaked rounds sealed and cool. They dry out in open air and shrink back toward the size that does not work.

Get this right once and it becomes a five minute job the night before. Get it wrong and the game becomes an afternoon of clearing jams, which is where most of the bad reviews of gel blasters come from.

Looking after a Nerf GelFire blaster

Water and mechanisms are not natural friends, so a Nerf GelFire blaster needs a habit a dart blaster never does. Five minutes after a game saves a repair later.

• Empty the hopper after every session. Rounds left inside dry out, stick together and start the next game with a jam
• Let it dry open. Trapped moisture is what corrodes contacts and springs
• Clear a jam gently. A burst round leaves gel behind, and forcing the mechanism turns a two minute clean into a broken part
• Rinse the feed path occasionally. Dried gel builds up where you cannot see it

Do that and the blaster lasts. Skip it and the first jam of the second season is usually the last thing it does.

What a season of Nerf GelFire actually costs

The running cost is genuinely different from darts, and it runs in the opposite direction to what people expect.

Ammunition is cheap per shot. Fifteen thousand rounds in a single refill is not a number any dart pack reaches, and the price per round is a fraction of a dart.

Nothing is recoverable. Every round is spent on impact, so consumption is total rather than partial.

The blasters cost more up front. This is a Nerf Pro line rather than a supermarket line, and the pricing reflects it.

Add it up over a summer and Nerf GelFire is usually cheaper to run than a dart game with the same number of players, purely because nobody is replacing lost darts every fortnight.

Who should buy into Nerf GelFire

Three clear cases for Nerf GelFire, and one clear case against.

Buy it if dart collection is ruining your games. This is the whole reason the product exists, and it delivers on it.

Buy it for teenagers and adults with space outside. A garden, a field, somewhere the water does not matter.

Buy it if you want a summer game. Wet, fast, and the glow in the dark rounds make an evening game genuinely good.

Do not buy it for younger children or for indoor play. The age rating and the water both point the same way, and a dart blaster is the better tool for that job.

If you are buying for a mixed age group, run two games rather than one. Dart blasters for the younger half, and if you want a shareable list of the right gear our Nerf wish list puts the matching ammunition on automatically.

Which Nerf GelFire blaster to buy first

Eight blasters is a small enough line that the choice comes down to how you intend to play rather than to spec sheets.

Playing with one other person. The Dual Wield two pack solves the whole problem in one purchase. Two matched blasters, one ammunition type, nobody arguing that the other one is better.

Playing in a group. Buy the same model for everybody if you can. Matched blasters keep a game fair, and with gel rounds there is no dart advantage to argue about, so the blaster is the only variable left.

Buying one to try the format. The Mythic is the launch model and the one that got covered in the press, so it is the easiest to find information about and the easiest to sell on if the format is not for you.

Buying secondhand. Check the hopper and feed path for dried gel before anything else, ask whether it has been stored empty, and treat any blaster sold with rounds still inside as a repair job rather than a bargain.

One thing not to do: buy a Nerf GelFire blaster as somebody’s only blaster. The preparation time makes it a planned game rather than a spontaneous one, and most households want something they can pick up and fire in the garden without a night of soaking first.

Frequently asked questions

What ammunition does Nerf GelFire use?

GelFire Rounds, which are water based gel beads. They arrive dehydrated and must be soaked in water before they can be fired. Refill packs come in 5,000 and 15,000 round sizes.

Do GelFire blasters fire darts?

No. Nerf GelFire blasters fire gel rounds only. No dart of any brand or size works in them, and gel rounds do not work in a dart blaster.

How long do GelFire rounds take to soak?

Hours rather than minutes. Soak them the night before a game and they will be ready when you are, which is the practical habit most players settle into.

Does it hurt?

At 150 FPS a gel round is felt, which is why the line carries a 14 and up rating and why eye protection is not optional. The slower grey trigger versions fire at around 100 FPS.

Can you play GelFire indoors?

You should not. The rounds burst and leave water and polymer fragments behind, which is a mess on carpet and a slip hazard on hard floors.

How many GelFire blasters are there?

Eight, released between 2022 and 2024, plus a MrBeast branded version of the Mythic. Two ammunition refills exist, standard and glow in the dark.

Can you reuse GelFire rounds?

No. They burst on impact, which is the point of them. That is also why refills are sold in packs of thousands rather than dozens.

Do GelFire rounds stain?

They are water based and clear, so staining is not the usual complaint. Wet clothing and a damp patch on the ground are, so play outdoors and expect people to finish the game damp.

Is GelFire the same as other gel blasters?

The ammunition works on the same principle as other gel bead blasters. What differs is that this line is sold as a mainstream toy under Nerf Pro, with the age rating and the regional trigger rules that come with that.

Do you need a hopper full of rounds for one game?

More than most people expect. Every round is spent when it lands, so a single game gets through hundreds, and a refill of 5,000 is a sensible starting quantity rather than a bulk indulgence.

Can younger children play Nerf GelFire under supervision?

The line is rated 14 and up, and at around 150 FPS that rating is doing real work. For younger players a standard dart blaster is the right tool, and our Elite Jr guide covers the line built specifically for small hands.

Is GelFire waterproof?

The ammunition is water, so the blaster copes with getting damp. That is not the same as being waterproof, and the maintenance habits above exist precisely because water and mechanisms do not mix indefinitely.

Does GelFire work in cold weather?

Soaked rounds are mostly water, so a hard frost is not their friend. Prepare them indoors and keep them sealed until you play, rather than leaving a tub outside overnight in winter.

Where does this information come from?

The product list, dates and specifications come from the community Nerf wiki and Hasbro’s own refill listing. Anything we could not verify was left out rather than guessed at.
