Product Compatibility

Are WE Hi-Capa 5.1 and 4.3 magazines interchangeable?

No. The WE Hi-Capa 5.1 uses 30-round magazines while the 4.3 uses shorter 28-round magazines — they are size-specific and not interchangeable. Always match the magazine size to your pistol model.

Are WE 1911 and Hi-Capa magazines interchangeable?

No. Although they look similar, the 1911 uses single-stack magazines while the Hi-Capa uses double-stack magazines. The magazine wells are different widths, so they cannot be interchanged. Always match the magazine to your specific model.

Can CO2 and green gas magazines be used interchangeably? For example, MG-92C vs MG-92G?

No. CO2 magazines and green gas magazines have different internal structures (valves and seal pressure ratings). The MG-92C (CO2 version) only works with CO2 magazines, and the MG-92G (green gas version) only works with green gas magazines. Mixing them can cause leaks or damage.

How many versions of WE M9 magazines are there, and which guns do they fit?

WE M9 magazines come in three main versions: MG-92G (green gas standard, 25–28 rounds depending on version), MG-92C (CO2 version, 25 rounds), and extended versions. They are not interchangeable across versions — match the magazine to your gun's gas type. Drum magazine versions for the M9 series are also available.

Which gun models do drum magazines fit?

WE drum magazines are model-specific, such as 1911 drum, Hi-Capa drum, and M9 drum versions. Drums are model-specific within each gun family — check the listed compatible models, as magazine sizes vary (e.g., Hi-Capa 4.3 vs 5.1). Check the listed compatible models before purchasing.

Gas Selection

What is the difference between green gas and CO2? Which should beginners choose?

Green gas is a lower-pressure gas (around 115 PSI) with softer recoil, ideal for beginners and indoor play. CO2 is high-pressure (around 800 PSI) with higher velocity and stronger recoil, suited for players who want more power. Beginners should start with green gas — it is also gentler on the gun's internals.

What should I do when my green gas gun won't cycle in cold weather?

This is normal — green gas vaporizes less efficiently in cold temperatures. Solutions: warm the magazine against your body before use, or switch to a CO2 version (CO2 is far less temperature-sensitive). For winter outdoor play, CO2 or HPA is recommended.

How many shots can I get from one 12g CO2 cartridge?

One 12g CO2 cartridge typically delivers 50–80 shots (about 2–3 pistol magazine fills), depending on ambient temperature and the gun's gas consumption. Carry spares with you.

How should I safely store green gas cans?

Store in a cool, ventilated place away from fire and heat (below 50°C / 122°F). Never leave cans in a sun-exposed car. Green gas is primarily propane and is flammable — handle with care.

Which is more stable, green gas or CO2?

CO2 is more stable. As a high-pressure liquefied gas, its output pressure is far less affected by temperature, delivering consistent performance year-round. Green gas is lower-pressure — below 15°C (59°F), its pressure drops noticeably, affecting trajectory and velocity. For all-season consistency, choose CO2. In warm environments or indoor play, green gas is perfectly adequate and more economical.

What is HPA? What are its pros and cons compared to green gas and CO2?

HPA (High Pressure Air) feeds the gun directly from an air tank via a hose, eliminating the need for gas-storing magazines. Pros: the most stable pressure output, unaffected by temperature, hundreds of shots per fill. Cons: requires carrying a tank and hose (reduced mobility) and higher upfront investment. Best for advanced players and competition use seeking maximum consistency. Airgrix carries Dominator HPA tanks and air lines.

BB Selection

What are 0.2g, 0.25g, and 0.28g BBs respectively suited for?

0.2g: higher velocity and flatter trajectory, best for close-quarters (CQB) and pistols. 0.25g: the best all-rounder with better wind resistance than 0.2g — the most popular weight for rifles. 0.28g and above: best for long-range sniping with the highest precision but lower velocity. Beginners should start with 0.25g.

Are heavier BBs always more accurate?

Generally yes, within limits. Heavier BBs retain velocity better and resist wind, producing tighter groupings at range. But excessively heavy BBs cause low velocity and severe trajectory drop. Every gun has an optimal weight: pistols typically use 0.2g–0.25g, rifles 0.25g–0.28g, snipers 0.3g and above.

Can steel BBs (4.5mm) and 6mm BBs be mixed or interchanged?

Absolutely not. 4.5mm steel BBs are for airguns, while 6mm BBs are for airsoft — different calibers and materials entirely. Mixing them will damage the barrel and can be dangerous. Airgrix lists these in separate categories; always check the product labeling.

Can moisture-damaged BBs still be used?

Not recommended. Moisture-damaged BBs may have uneven surfaces, causing accuracy loss, jams, and potential inner barrel damage. Store BBs sealed in a dry place and use them reasonably soon after opening.

Can used BBs be reused?

Not recommended. Fired BBs develop surface wear, deformation, and pick up dust and debris. Reusing them causes severe accuracy loss, jams, and can scratch precision inner barrels. BBs are consumables — always use fresh ones. Please clean up fired BBs responsibly and don't leave them on the field.

Legal & Shipping

Is there an age restriction for buying airsoft guns in the US?

At the federal level, buyers must be 18 or older. Airgrix sells all airsoft products to customers aged 18 and above only — age confirmation is required at checkout.

Does Airgrix have shipping restrictions to certain states?

Airgrix currently ships to most US regions. However, some cities (such as New York City) have additional replica firearm restrictions — check your local regulations before ordering. Contact customer service if you're unsure.

Do airsoft guns require orange tips?

Under federal law, airsoft guns must have an orange tip marking at the time of sale. All products sold by Airgrix comply with federal requirements. Do not remove the orange tip yourself, as this may violate the law.

Maintenance

How often should GBB pistols be maintained, and what oil should I use?

Perform basic maintenance every 500–1,000 rounds or monthly. Use silicone oil to lubricate slide rails and valve seals. Never use petroleum-based lubricants like WD-40 — they corrode rubber seals.

How do I fix a leaking magazine?

First check whether the valve and fill-port seals are worn — apply a few drops of silicone oil to see if the seal recovers. If leaking persists, the seal is likely damaged and needs replacement with the correct model's seal kit. WE magazine seal kits are available in-store, and most replacements are DIY-friendly.

How should I store guns and magazines when not playing for a long time?

Leave a small amount of gas in magazines (not fully empty, not fully charged) to keep seals conditioned. Wipe down the gun and store in a dry place. Store green gas cans and CO2 cartridges separately, away from heat.

What causes weak slide cycling?

Common causes: low gas (refill), worn recoil spring (replace), dry slide rails (apply silicone oil), or cold weather (insufficient green gas pressure). Troubleshoot in this order — most cases are easily resolved.

Beginner's Guide

What GBB pistol is recommended for beginners?

The WE 1911 or WE M9 series: classic designs, abundant parts availability, affordable pricing ($100–$130), and forgiving for newcomers. The Hi-Capa 5.1 is more competition-oriented but slightly pricier. Start with a green gas version.

What are the essential accessories for beginners?

One can of green gas, 0.25g BBs, full-seal goggles (mandatory), and silicone oil. None are expensive, but all are essential. Eye protection is the non-negotiable safety baseline — don't skip it.

What do GBB, AEG, and CO2 mean?

GBB (Gas Blowback): gas-powered with realistic recoil feel. AEG (Automatic Electric Gun): battery and motor driven, common for rifles. CO2: versions powered by CO2 cartridges, delivering higher power. They are three different power systems.

How does operating an airsoft gun differ from a real firearm?

The manual of arms is similar (charging, safety, magazine release), but airsoft has no lethal capability. Safety rules are equally strict: always treat the gun as loaded, never point at anyone (except on-field with full protective gear), and keep your finger off the trigger until ready to fire.
