CARBON HPA META FLASCHE™¹
CARBON HPA TANK SO LIGHT YOU WON'T EVEN FEEL IT IN A CQB ROOM — 410 GRAMS.
Dual-layer construction that withstands 50 drops on concrete. First series HOLLOW VERSION.
PICTURE THIS.
You are the point man of the team. Going through the door.
A room behind the door. An opponent in the room. He sees you at the exact same moment you see him.
A fraction of a second. Two possibilities — either you raise your gun and he goes down, or vice versa.
And do you know what separates these two possibilities? Not your reflexes. Not training. Not the gun in your hand.
The weight you are carrying on your back.
That kilogram doesn't matter on the first shot. It matters in the fourth hour of the game, when your reflexes remain the same as in the first hour — but your opponent's don't.
THIS TANK IS NOT FOR EVERYONE.
It's not for the player who rents a gun twice a year and plays three games. A rented aluminum brick from the field is enough for them.
It's not for the player who buys the cheapest gear justifying it with "it's just airsoft." They will buy an uncertified Chinese carbon tank, the gel coat will crack on their first drop in the arena, and they'll complain that "all carbon cracks."
This tank is for you if:
- You are the type of player who goes through the door first. Not out of duty — of your own free will.
- You are the type who knows that a CQB duel isn't decided by gun accuracy. It's decided by a fraction of a second between a silhouette appearing in your line of sight and raising your weapon to shoot.
- You are the type who doesn't treat gear as a necessity — but as an extension of your body.
- You are the type who leaves the arena after four hours feeling useful — not just like you survived.
- You are the type of player the captain sends into the room first — not out of sacrifice, but out of trust.
If you read this and something inside you said "yes, that's me" — keep reading. The rest of this page will explain exactly why our 0.36-liter tank is the tool you need.
DO YOU KNOW WHY PLAYERS PUT NEOPRENE COVERS ON CARBON TANKS?
You might think: for a better grip. Yes. That too. But that's only half the truth.
The other half is uncomfortable.
They put it on because somewhere deep down, they know the surface is weak. That cover is actually an admission. Silent fear wrapped in neoprene.
And that fear is justified.
On a standard carbon tank, between the hard world and the pressurized core, there is only a single structural wall and a layer of clear coat. That is all that protects your air, your regulator, and your head.
One deep scratch through that clear coat — and the fill station will refuse to fill it. Overnight, an expensive piece of gear becomes a useless paperweight.
Imagine two helmets worn over each other. The outer one takes the impact. The inner one keeps protecting. That is exactly how our tank works.
That's why you can use it without a neoprene cover. Why you can throw it into your backpack without a second thought. Why, when it drops, your mind won't panic with "please, don't crack."
- Exactly one kilogram lighter than your aluminum brick — and what that single kilogram does to your corner turn in the first hour of play compared to the fourth.
- Burst test where our tank only gave way at 1,016 bar — more than three times the 300 bar working pressure you'll fill it to. Why this means you can toss it into your pack without a second thought.
- Why our custom 650 PSI primary regulator recovers line pressure faster than the industry-standard 800 PSI regulator — and what that does for your second and third rapid shots when breaching a room.
- 50 drops onto concrete from shoulder height, fully pressurized, on the bottom, side, and valve area — without a single crack in the load-bearing structure. Why in CQB, where your pack gets handled 30 times a game, you need exactly this.
- Why you'll never need to put a neoprene cover on this tank — and what that says about surface quality when compared to the one you currently have at home.
- 500 bar tested on every single unit before leaving the workshop. Not a "tested batch." Every single one. Why this is the difference between carbon you can trust and carbon you just hope holds up.
- Six international certifications that ensure no fill station can reject your tank: ISO 11119 · DOT CFFC · EN 12245 · GB 28053 · CE · TS. Why when playing abroad, this is the difference between playing and sitting in your car.
- Why the manufacturing time for a single tank is 3 days — and how much of that goes into carbon curing that physically cannot be rushed. Physics doesn't listen to marketing.
- Fixed (non-rotating) fill valve aligned precisely 180 degrees opposite the pressure gauge — a small design detail that tells you how much thought the developer put into things only an experienced player notices.
- Convex (not flat) burst disks on both sides of the regulator. Why this increases your safety margin — and why cheap carbon lacks this.
- Why it mounts directly onto your META low-pressure regulator and line — no adapters, no modifications, no trip to the workshop before a weekend event.
- 15-year statutory lifespan. Why when calculated per season, the price makes sense after you recalculate it in your head five times before believing it.
TESTING OUR TANK WENT THROUGH
- 300 bar — working pressure you will fill it to.
- 500 bar — pressure we test every single tank at before it leaves the workshop.
- 1,016 bar — burst test failure pressure. More than three times the working pressure.
- 50 drops from shoulder height onto concrete, fully pressurized, on the bottom, side, and valve area. Not a single crack in the structural core.
- 6 months in competitive players' hands before release. Every weekend. Hundreds of fills. Zero failures.
CERTIFICATIONS
Six international certifications you can verify yourself:
ISO 11119 · DOT CFFC · EN 12245 · GB 28053 · CE · TS
This is the difference between a tank a professional fill station operator fills without a word — and a tank they turn away.
INDEPENDENT REVIEWER
We gave the complete setup to Czech video creator Nakashi for testing.
We'll admit it right away: we collaborate with him. That's exactly why we didn't dictate a single word. We told him just one thing: "Try it out. And tell the truth — even if it's uncomfortable."
His conclusion: "Dostanete všechno, co je k sobě kompatibilní… nemusíte se bát, že by vám něco chybělo nebo že něco budete mít nekompatibilního."
He summarized the whole set in three words: "very user-friendly."
REVIEW FROM A PILOT BATCH PLAYER
YES. THIS TANK COSTS MORE THAN CHEAP CARBON. I'LL TELL YOU EXACTLY WHAT FOR.
Not for the material itself. The carbon fibers we use are comparable to premium competitors. The difference isn't the raw material — it's what we do with it.
- For the construction. Dual-layer carbon winding is slower, demands more precision, and requires two separate curing cycles. Cheap carbon doesn't do this.
- For three days of manufacturing per single unit. Most of this time is carbon curing — and that physically cannot be rushed. Physics doesn't listen to marketing.
- For testing every single unit to 500 bar before shipping. Not a "tested batch." Every single one. This adds time, labor, and reduces batch yield — but it's the only way we can tell you with confidence what you're holding.
- For European manufacturing. Not a Chinese manufacturer with a European logo. In-house development, in-house workshop, full responsibility.
- For a 15-year statutory lifespan. Certified, with a five-year hydrostatic inspection cycle. Not "will last a few years." Fifteen years, provably.
AND ONE MORE THING ANOTHER SELLER WON'T TELL YOU:
You will never get a discount on this tank. No Black Friday. Never.
Our price was never inflated. You buy today — you pay the exact same as every other serious player who bought it before you, and every other who buys it after you. That is respect — to you and to everyone who carries it.
WHAT YOU GET IN THE PACKAGE:
- Carbon HPA tank 0.36 L — 410 g — HOLLOW VERSION design — €239.99
- Custom 650 PSI primary regulator — factory pre-set — convex burst disks on both sides — fixed fill valve 180 degrees opposite pressure gauge — included
- 500-bar individual quality test before shipping — included
- Six international certifications + tank registration for 15-year hydrostatic cycle — included
- 30-day no-questions-asked money-back guarantee — included
- 15-year statutory lifespan — included
Do the math: €239.99 divided by 15 years = roughly €16 per season.
Less than a single entry fee to a larger field.
You buy this one once.
I’ll give you 90 days. Play at least five real games with it — not five minutes in your backyard.
If you don't feel the difference, send it back to me. I'll refund every euro. I'll even pay for shipping.
And if you really gave it those five games and the result was zero — write me a few sentences about where you played. I'll refund you double. Not 260 euros. 520 euros.
Either I stand behind it 100%, or I'm doing it wrong.
Imagine your first game with this tank on your back.
You are the type of player who enters a room a fraction of a second faster than the opponent.
You are the type of player your squad leader pushes first into every tough breach — because they know you'll be there and hold out.
You are the type of player they talk about in the car on the way home: "Did you see how he appeared around the corner? Nobody saw him coming."
You are the type of player who looks like they just started at the end of a six-hour game — while the opponent's best shooter is wheezing like a bellows at the compressor.
You are the type who doesn't see CQB as a mere hobby, but as a discipline. And your gear needs to reflect that seriousness.
This tank won't make you a better player. You have to do that yourself. But it will stop being the thing standing between you and your best game.
This is the first series of the HOLLOW VERSION. The first carbon batch X Custom has ever released. We have never sold carbon before. We spent a year and seven months working on it before deciding it was ready to bear our name.
Three days per piece. Limited workshop capacity. The batch is small.
Once it runs out, the next batch won't arrive for several months. Carbon curing physics physically cannot be rushed.
And the second thing is about you.
Every weekend you delay is another game where an aluminum brick drags you down on every corner turn. And you lose duels you could have won. Nobody is going to give those games back to you.

What if something cracks after a year?
Why is it more expensive than Chinese carbon on AliExpress?
Isn't 0.36 L too little air for a longer game?

First series HOLLOW VERSION. Shipping to Czechia & Slovakia in 1–2 business days.
If you came to this page looking for a carbon HPA tank for long games, you already know why you're here.
You know your aluminum tank costs you time on the front line. You know carbon is the way forward. The question isn't "whether carbon", but "which carbon".
You have three options:
Make your choice. But choose so that in the fourth hour of the game, you're holding your position — not standing in line at the compressor while the enemy takes your field.
I've been running a Hi-Capa with an HPA adapter for about a year and a half. Initially I borrowed an aluminum tank from a buddy, then tried cheap carbon from AliExpress — which cracked on the gel coating after three games, so I looked for something solid.
I knew about X Custom from Nakashi's video. I wondered if 0.36L would be enough — but for a Hi-Capa it's surprisingly plenty, a pistol just doesn't consume as much air as a rifle. I only refilled twice during a full day of play.
The 650 PSI output regulator caught my eye — reducing seal wear on HPA conversions is something we deal with all the time. That was the tipping point for me.
Downside: delivery took a day longer than promised. Minor detail, but worth mentioning.
I had the starter set with the aluminum tank from X Custom for about a year. It worked fine, but after every indoor CQB game, my back was aching by the end.
So I ordered the 0.36L carbon tank. First thing I noticed when picking it up — literally nothing. I mean, I barely felt it. Teammates were asking what was new because my pack looked lighter.
Drawback — the price. I hesitated for a long time. But after the first game, I realized I should have bought it way sooner. Highly recommend to everyone.
The weight difference is noticeable. The backpack is simply lighter. I don't know how to describe it better. The weight just isn't there and it feels great.
Compatibility with META — no issue, everything clicked together perfectly.
Haven't dropped it on concrete intentionally yet, but during one fall in the arena nothing happened. Gel coat still looks like new. Recommend.
I previously had an HK Army Redline with an aluminum tank. The system worked, but the tank was heavy enough that it always bothered me — especially on longer games.
What convinced me to get X Custom more than just the weight was the regulator spec — 650 PSI custom design instead of standard 800 PSI. Since I'm into mechanics, that was a solid argument for me, not marketing.
First impression after delivery: quality is very good. Carbon is uniform with no defects. The skeleton artwork looks different than anything else on the market.
Sat on the META regulator with no issues, soft hose worked without changes. No adapters needed.
Only thing — shipping time was a bit longer than I expected. But it was worth it.
