1.5-LITER CARBON HPA TANK THAT HOLDS ALMOST 3× MORE AIR THAN YOUR ALUMINUM 48CI — AND WEIGHS 40% LESS.
Dual-layer construction. First series HOLLOW VERSION.
IT'S THE THIRD HOUR OF THE GAME.
You are standing on the front line of your sector. Rifle ready. You have air. You are in the zone.
Forty meters away from you, by the compressor, stands their best shooter. Refilling his tank. Two more are waiting behind him.
By the time they get back, you're already at the third position. Their captain just realized he's missing three shooters and the right flank is open. He calls them back. Too late.
Your team pushed the line thirty meters forward. Not because you're better shooters. Because you were there while the opponent was huffing at the compressor.
THIS TANK IS NOT FOR EVERY HPA PLAYER.
It's not for the player who rents a gun twice a year. Anything that holds air is enough for them.
It's not for the CQB player who needs an ultra-lightweight tank for twenty-minute indoor skirmishes. For them, we have the 0.36-liter model.
This tank is for you if:
- You are the type of player who stays on the field all day. Not for an hour, not three. All day.
- You are the type of player who treats MILSIM as tactics, not a chase — and knows that games are won by position, not speed.
- You are the type the captain relies on. He knows where to find you. He knows you'll still be there in the fourth hour.
- You are the type of player who doesn't want to be the one the team asks "where were you?" — you want to be the one they say "thanks to him, we held the line."
- You are the type who knows that between 200 bar of aluminum and 300 bar of carbon, there is a difference of a whole game you wouldn't otherwise finish.
If you see yourself in this — keep reading. The rest of this page will tell you exactly why our 1.5-liter tank is the tool you need.
- Why 40% less weight on your back all day means the difference of one full game your back can still handle — and what that means for Sunday mornings you used to lose to recovery.
- Burst test where our tank only gave way at 1,016 bar — more than three times the 300 bar working pressure. Why this means you can hit the toughest MILSIM event without second thoughts.
- Nearly 3× more air than your aluminum 48ci — which in practice means refilling once instead of three times during a full-day MILSIM. Why those three players waiting ahead of you at the compressor will no longer cost you position.
- Why our custom 650 PSI primary regulator recovers line pressure faster than the industry-standard 800 PSI regulator — and what that means for your rate of fire during a six-hour game.
- 50 drops onto concrete from shoulder height, fully pressurized, on the bottom, side, and valve area — without a single crack in the structural core. Why in MILSIM, where a single game lasts six hours and your pack gets tossed 30 times, this is exactly what you need.
- Why you'll never need to put a neoprene cover on this tank — and what that says about surface quality when you compare it to the one you currently have at home.
- 500 bar testing on every single unit before leaving the workshop. Not a "tested batch." Every single one. Why this is a completely different level of trust for MILSIM.
- Six international certifications that ensure no fill station can reject your tank: ISO 11119 · DOT CFFC · EN 12245 · GB 28053 · CE · TS. Why at MILSIM events in Germany, Austria, or the Czech Republic, 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.
- Fixed (non-rotating) fill valve aligned precisely 180 degrees opposite the pressure gauge — a subtle design detail showing how much thought was put into every element only experienced players notice.
- Convex (not flat) burst disks on both sides of the regulator. Why this increases your safety margin during repeated pressure cycling — which happens ten times more in MILSIM than CQB.
- Why it mounts directly onto your META low-pressure regulator and line — no adapters, no modifications, no trip to the workshop before weekend MILSIM.
- 15-year statutory lifespan. Why when broken down per season, the cost makes sense the second you calculate it in your head.
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 in Germany or Austria 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 1.5 L — 860 g — HOLLOW VERSION design — €259.99
- 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: €259.99 divided by 15 years = roughly €17 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 MILSIM event with this tank on your back.
You are the type of player who, in the fourth hour of the game, is still holding your position — while the enemy has to rotate sectors because they ran out of air.
You are the type whose squad leader won't pull you off the front line to refill. They know you'll hold out.
You are the type they talk about in the car after the game: "Thanks to them, we held the southern sector. They were there the whole time."
You are the type who looks like they just started at the end of the game — while the opponent's gunner is wheezing like a bellows at the fill station, cursing their aluminum tank.
You are the type who doesn't see MILSIM as casual fun, but as a test of focus and endurance. And your gear needs to reflect that seriousness.
This tank won't make you a better tactician. You have to do that yourself. But it will stop being the reason you couldn't be where your team needed you.
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 MILSIM spent waiting in line at the compressor while the enemy takes your zone. Nobody is going to give those MILSIMs back to you.

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.
