Frequently Asked Questions – Airsoft & Airguns

Hop Up is a mechanism that applies backspin to the BB. Backspin lifts the BB’s trajectory and increases range, helping it fly further and on a straighter line.

In most airsoft guns Hop Up is adjustable, so you can tune it to match the BB weight you’re using. Hop Up is also commonly referred to as hop, hopup, or Hop-Up.

Blowback can be found on some gas and electric airsoft guns. It means the slide or bolt moves back and forth when firing – similar to real firearms. This adds realism, but it can also cause slightly more wear over time.

All guns we sell use 6 mm bio or standard plastic BBs. BB weight is chosen based on your gun’s power and the range you want. A helpful guideline:

• under 0.5 J → 0.12 g
• 0.5–1 J → 0.20 g
• 1–1.5 J → 0.25 g
• 1.5–2 J → 0.28–0.35 g
• 2–2.5 J → 0.35–0.40 g

In general, the more powerful the gun, the better and more stable heavier BBs perform.

Bio BBs start breaking down due to sunlight, moisture, and heat. In Finnish conditions, degradation typically takes about 1–2 years.

Keep bio BBs sealed in their bag or bottle so they don’t absorb moisture and become soft or brittle.

We don’t recommend it. Cheap BBs are the most common cause of jams and broken guns. Low-quality BBs often have:

• a visible seam line
• an uneven or oval shape
• a rough or porous surface
• bright “toy-like” colors

Use only high-quality, seamless BBs from well-known brands (e.g. G&G, Marui, etc.) to keep your gun reliable and accurate.

Range depends on the gun, joule output, and BB choice, but generally:

• basic spring guns: around 20–50 m
• standard AEG (about 1 J): around 30–50 m
• sniper rifles and upgraded guns: around 40–70 m

Power isn’t everything – good Hop Up tuning and the right BB weight are just as important as joules.

• Standard gas pistols/rifles: don’t work properly below +5 °C because the gas won’t expand enough.
• Electric guns (AEG): work, but the battery and Hop Up rubber suffer in the cold → range and rate of fire can drop.
• CO2 guns: usually perform better in cold weather than standard gas guns.

Also remember that plastic parts can become brittle in extreme cold.

Yes. All products have a 6-month material and manufacturing defect liability. This covers faults that were already present at the time of sale. Damage caused by use, wear, misuse, upgrades/mods, or incorrect BBs is not covered.

Unfortunately, we do not take used guns for resale or trade-in.

We ship orders via Matkahuolto. Parcels are typically routed to your nearest Matkahuolto pickup point or partner store (such as K-Market, R-Kioski, etc.). Available delivery methods and prices are always shown at checkout.

You’ll receive an automatic order confirmation email when your order is successful. Make sure your email address is correct and that you monitor your inbox.

• You’ll receive a tracking number by email once your order has been processed and shipped.
• Matkahuolto will send an SMS when the parcel is ready for pickup, including the pickup location.

Current shipping costs are always shown in the cart and at checkout. We typically use a flat fee (e.g. €6.90) regardless of order weight. Hazardous goods (e.g. smoke grenades, BB grenades) add a dangerous goods handling fee (e.g. €3.30). If you use bus COD (bussiennakko), an additional fee applies.

Electric guns (AEG): Many manufacturers follow Tokyo Marui standards, so magazines are often cross-compatible within the same platform (e.g. M4, AK). Small fitting differences can still happen.

Gas and spring guns: Magazines are often brand- and model-specific, so a different brand magazine usually won’t fit even if the gun looks similar.

If you’re unsure, ask us before buying.

Hi-cap (High Capacity) magazines hold significantly more BBs than standard mags. BBs are stored in a reservoir and fed by winding a wheel at the bottom (“winder”).

Important: Do not load a hi-cap through the feed lips with a speedloader – it can damage the magazine.

Mid-cap (Middle Capacity) magazines look like standard mags and feed similarly, but hold more BBs (typically around 100–150). They don’t require winding and feeding is often very reliable.

Regular-cap magazines typically hold around 50–80 BBs. They are very reliable and closer to realistic capacities than hi-caps.

Real-cap magazines mimic real firearm capacities, usually around 15–50 BBs. They are popular in milsim and scenario games where realism matters.

Drum or box magazines are very high-capacity magazines, typically holding 500–5000 BBs. Feeding can be:

• manual (winding wheel)
• electric (button or auto-feed linked to trigger firing)

Important: Do not load drum/box magazines through the feed lips with a speedloader – it can damage the feed mechanism.

Basic maintenance after every game day:

• Clean the inner barrel using a cleaning rod and a clean cloth.
• Empty BBs from magazines.
• Charge AEG batteries properly.
• Lubricate gas gun seals with silicone.
• Store CO2 magazines empty after shooting.
• For standard gas magazines, it’s good to store a small amount of gas inside since it contains silicone that helps lubricate seals.

Use only pure silicone oil:

• For barrel cleaning (a very small amount)
• For lubricating seals

Do not use gun oils, CRC, or solvent-based oils – they can damage rubber and plastic.

Plastic parts can be wiped with a slightly damp cloth. For tougher dirt, use diluted dish soap water.

Never submerge the gun in water and always dry it carefully.

NiMH battery:

• Durable and safer for beginners.
• Available in different shapes: mini, large, stick (AK type), crane stock.

LiPo battery:

• More powerful but more sensitive to misuse.
• Smaller physical size → fits more guns.
• Requires a LiPo-compatible charger and careful handling.

Performance-wise, a 7.4V LiPo is roughly comparable to a 9.6V NiMH. For beginners we recommend NiMH batteries.

As a rule of thumb for a standard AEG (about 1 J):

1 mAh ≈ 1 shot

For example, a 1400 mAh battery gives roughly 1400 shots.

More powerful setups and cold weather will drain batteries faster. Battery and gun age/condition also affect performance.

With a basic charger:

Charging time (h) = battery capacity (mAh) / charger current (mA)

Example: 1400 mAh battery with a 300 mA charger → 1400 / 300 ≈ 4.6 h → about 5 hours.

The battery may warm slightly while charging. When it becomes clearly warm to the touch, it’s usually full – don’t keep charging much longer.

Important:

• Never leave batteries charging unattended.
• Charge LiPo batteries only with a LiPo-compatible automatic charger.

Modern NiMH and LiPo batteries don’t really have a “memory effect”, so full discharging isn’t necessary. With LiPo batteries, make sure the voltage doesn’t drop too low.

Yes. It’s a good idea to recharge about every 3–5 months so the battery doesn’t discharge too deeply and get damaged. For LiPo batteries, storage charge level is commonly used for long-term storage.

Check first:

• Is the barrel clean?
• Is the Hop Up adjusted correctly?
• Are you using the right BB weight?

If there isn’t enough Hop Up, BBs may drop after 10–20 meters. When tuned correctly, the BB starts to “glide” and the effective range increases noticeably.

• Check the battery charge – try another battery if possible.
• Check the fuse near the battery connector. If the fuse wire is broken, replace it with the correct rating.
• If nothing helps, don’t force it – contact the shop or service.

• Tap the magazine gently on the side and bottom.
• Try firing the gun upside down. If it works upside down, the issue is often the magazine.
• For hi-caps, make sure you’ve wound the wheel enough (10–20 seconds) and keep winding during use.
• Check the barrel for a jammed BB (use a cleaning rod).

Low-quality BBs and dirt in the magazine can easily cause jams.

• Check that the magazine has gas.
• Remember gas guns don’t work well in cold weather (below +5 °C).
• If you shoot a lot in a short time, the magazine cools down → gas won’t expand properly. Let it warm up and try again.

• Make sure you’re using strong enough gas (metal-slide pistols often require stronger gas).
• Check that there’s no debris or blockage in the magazine.
• Check that the barrel isn’t blocked.

• Check for a possible barrel jam.
• Tap the magazine gently on the side and bottom.
• Try firing upside down – if it works then, the issue is often the magazine.

Stop using it immediately. Do not keep firing.

Contact the shop or service – continuing to fire can make the damage significantly worse.

• The 6-month manufacturing defect liability ends if you open or upgrade the gun yourself (except basic field stripping without tools).
• Hop Up adjustment, normal field stripping, and removing a gas gun slide according to instructions are okay.

If you’re not sure what you’re doing, we recommend using a professional.

You can print a separate consent form for a guardian to sign. With this permission, a minor can purchase airsoft guns from ProAirsoft stores without the guardian being present.

Consent Form (PDF)

Yes. Adults (18+) may own an air pistol without a license within certain caliber limits.

Yes. Adults can buy an airgun without a permit when the caliber is up to 6.35 mm / .25.

No. Airguns with a caliber up to 6.35 mm / .25 can be purchased without a permit, but the buyer must be at least 18 years old. Minors may use airguns only under adult supervision.

In Finland, airguns may not be used to hunt game animals. The only exception is pest control indoors (voles, rats, mice).

No, magazines are permit-free.

No. In Finland, you may not hunt squirrels or other game animals with an airgun. Only certain pests indoors are an exception (voles, rats, mice).

Yes, if you are an adult. Minors may shoot under adult supervision, and the person in possession of the gun is responsible.

You cannot carry an airgun openly in public. It must be transported covered (e.g. in a gun bag) to and from the shooting location. Finnish public order law restricts carrying firearm-like items in public without a valid reason.

You can use an air rifle at shooting ranges and on private land when safety is ensured. Shooting in public places, residential areas, or anywhere that could endanger others is prohibited.

We recommend:

• out of children’s reach
• preferably in a locked cabinet or room
• unloaded, without ammo
• in a dry place to prevent rust

Even though airguns are not regulated as strictly as firearms, the same safety principles are recommended.

Adults generally do not need a possession permit for standard airguns within the applicable caliber limits.

Yes. However, we still recommend storing it in a locked space or otherwise secured so unauthorized persons cannot access it.

A gas airgun uses gas or compressed air to fire. These are not firearms, but they can still be dangerous if misused – so follow safety instructions and recommended storage practices.
