Welcome to the heavy weight department. If you have made the jump to running a gas blowback rifle, you already know that your magazines are the single most important part of your entire setup. Unlike a plastic electric mid-cap, a proper airsoft gas magazine does far more than just feed BBs; it houses the actual fuel tank and valve system that powers the heavy recoil of your rifle. Because they do the heavy lifting, having reliable, well-maintained mags is what keeps you in the game.
We stock a premium selection of Airsoft GBB Rifle Magazines designed for the most popular platforms on the market, including Tokyo Marui, WE, VFC, and GHK. Whether you need standard metal STANAG styles, modern polymer lightweight casings, or specific platform spares, we have got you sorted
If you are transitioning from electric guns, the price and weight of a gbbr magazine can be a bit of a shock. A standard electric mag is just a plastic shell with a spring, but a gas rifle magazine is a serious piece of engineering. The entire core of the magazine is a thick, cast-alloy pressure vessel designed to hold liquid green gas or CO2 under immense pressure safely.
Inside that alloy shell, you have complex internal components like input valves at the base, high-flow output valves at the top, and robust rubber seals. This heavy metal construction is why a loaded gas magazine feels exactly like a real, loaded firearm magazine. It adds a massive layer of realism to your loadout, but it also means you need a proper tactical vest or plate carrier to support the weight of carrying four or five spares out into the field.
This is the biggest trap for players looking to buy spares. There is absolutely no such thing as a universal gbbr magazine. Even if two different brands make an M4 rifle, their gas magazines will almost never interchange because the gas router seals on top must align perfectly with the loading nozzle inside the rifle receiver.
For example, a Tokyo Marui MWS magazine uses a specific square-profile rubber router designed solely for the Marui Z-System. If you try to shove a WE open bolt mag or a VFC mag into an MWS rifle, it either won’t lock into the magwell, or it will instantly leak gas and smash your loading nozzle. Always double-check the exact brand and generation of your rifle before buying. If you are running an aftermarket receiver kit, feel free to give us a shout at the shop first and we can confirm exactly which shell fits your build.
When you are skirmishing with gas blowback rifles, you have to completely change your mindset regarding ammunition management. Most standard gas rifle magazine options hold between thirty and forty-five BBs, mimicking the exact capacity of real-world assault rifles.
This low capacity is precisely why milsim players love them, as it forces you to communicate with your team, move under covering fire, and master your tactical reloads. However, because you only have around thirty shots per mag, the quality of the internal feed track is vital. High-quality brands use polished, friction-free polymer tracks to ensure that every single BB feeds flawlessly into the hop-up chamber without jamming, even when you are moving fast through thick brush or dirt.
Because gas magazines hold a realistic capacity of thirty to forty rounds, running just one or two mags will leave you dry very quickly. We generally recommend carrying at least four to five magazines on your rig, plus one in the rifle. This gives you around 150 to 200 rounds per game, which is plenty if you are picking your shots carefully and playing tactically with your squad.
Nine times out of ten, a leak from the top output valve is caused by a dry or unseated O-ring. Before you buy replacement parts, try purging the magazine. Hold the output valve open with your thumb, spray a small amount of pure silicone oil directly into the fill valve at the bottom, and let it cycle through. If that doesn’t work, you may need a standard valve key tool to gently tighten the valve threads, as they can sometimes vibrate loose during heavy full-auto firing.
You need to match your gas to the structural strength of your magazine and the ambient temperature. Heavy-duty metal magazines from brands like Tokyo Marui and VFC can handle higher-pressure winter gases easily when the UK weather drops towards freezing. However, running high-pressure black gas in the middle of a hot summer can create too much pressure, causing your rifle to drop in velocity due to valve-knocker lock, or even blowing out the internal rubber seals entirely. Stick to standard green gas when it is warm.
Green gas magazines have an internal reservoir that you fill from a large canister via a fill valve at the base. They offer smoother cycling and are easier to top up between games. CO2 magazines do not have a fixed gas chamber; instead, you screw a disposable 12g CO2 capsule directly into the side or bottom of the magazine. CO2 operates at a much higher pressure, giving you harder recoil and better performance in freezing weather, but the magazines require more frequent lubrication because CO2 is a completely dry gas.
No, the UK laws regarding airsoft defences only apply to the actual realistic imitation firearms themselves. Accessories, spare parts, and magazines are completely unrestricted, meaning anyone over the age of eighteen can purchase as many spare gas magazines as they need without needing a UKARA registration or a two-tone finish.
