UK Airsoft Law: Power Limits, IF, RIF, and Import Rules
If you are in the UK and looking at airsoft guns from overseas, there are a few legal points to understand first. Specifically, you should know about the firing power limits, IF and RIF classification, and a defense for import.
This page explains the legal basics in simple terms. It is written for UK buyers looking at airsoft guns and model guns, including items sourced from Japan.
UK and Japan Legal Energy Limits
The Guide on firearms licensing law provides guidance on how firearms are classified.
Specifically, Section 2.4 defines an airsoft gun as:
“…a barrelled weapon of any description which is designed to discharge only a small plastic missile … and is not capable of discharging a missile of any kind above the permitted kinetic energy thresholds…”
Kinetic Energy definition
The formula for Kinetic energy is Ek = 1/2mv2.
Ek is the energy in Joule [kg*m^2/s^2], m is the mass of the BB pellet, and v is the BB’s velocity.
In airsoft, the firing power of the gun is expressed in Joules.
A 0.20g BB is the most commonly used size.
For example, if a 0.20g BB is used, an energy value of 1.3J corresponds to roughly 114 m/s.
A higher Joule means a more powerful shot.
UK airsoft firing power limit
- 2 or more shots without repeated trigger pressure: maximum 1.3J
- Any other case: maximum 2.5J
*Guns exceeding a firing power of 2.5J are no longer treated as airsoft.
Such items are treated under firearms law instead.
Japan airsoft firing power limit
Japan’s kinetic energy threshold for airsoft guns is 0.98J.
Since Japanese airsoft guns are built below the UK airsoft thresholds, the firing power criterion is automatically cleared.
UK Airsoft Law: IF and RIF
UK’s Violent Crime Reduction Act 2006 (VCRA) distinguishes imitation firearms from realistic imitation firearms.

IF (Imitation Firearm)
An imitation firearm is an airsoft gun or model gun that does not closely resemble a real firearm in appearance. This often includes brightly coloured or clearly non-realistic designs, such as two-tone airsoft guns. Guns that clearly look like toys would generally fall into this category.
RIF (Realistic Imitation Firearm)
Under Section 38 of the VCRA, a realistic imitation firearm is an imitation firearm that:
“has an appearance that is so realistic as to make it indistinguishable, for all practical purposes, from a real firearm.”
For UK airsoft players, this distinction matters because most Japanese airsoft guns are sold in realistic finishes. Japan regulates firing power, but it does not require the bright two-tone appearance commonly seen in the UK market. As a result, many Japanese airsoft guns are likely to be treated as RIFs in the UK.
How to Import an IF or a RIF
How to Import an IF
There is no special defence requirement to import an IF.
How to Import a RIF
For most UK airsoft players, the practical route for importing or purchasing a realistic imitation firearm is UKARA.
UKARA (United Kingdom Airsoft Retailers Association) is the registration and verification system most commonly used to show that a buyer is a genuine airsoft skirmisher purchasing a RIF for permitted airsoft use.
There are other possible defences under the legislation, such as film, television, theatre, historical re-enactment, museum, gallery, and certain official government or police uses. We will skip those here since they do not apply to most ordinary airsoft players.
For a simpler practical explanation, see UKARA Explained.
What Happens If You Import a RIF Without a Valid Defence?
Under Section 36 of the VCRA, it is an offence to manufacture, sell, or bring a realistic imitation firearm into Great Britain unless a valid defence applies. Possible consequences include:
- seizure or destruction of the item by Border Force (customs)
- further checks or investigation by Border Force
- legal consequences if the case is pursued further
Buying Airsoft from Japan Can Still Go Wrong
Some airsoft businesses ship directly to overseas customers.
These businesses know what they are doing and there is not much to worry about.
However, most Japanese airsoft items are sold only for the domestic market.
To buy those items, overseas customers will need to use a proxy service.
Almost all Japanese proxy services ban airsoft completely because this category requires proper paperwork and a clear understanding of local import rules.
There are worse cases when a proxy allows the purchase, then refuses to ship the item later.
At that point, the customer can be left with no practical option other than domestic forwarding inside Japan or disposal of the item.
For UK buyers, the legal side is only one part of the process. The service route also matters.
If the service does not actually support airsoft properly, you will be wasting money for nothing.
About Us
Lunarcat grew up by helping customers who bought restricted items through other proxy services and had no way to ship internationally.
A big portion of these customers were purchasing airsoft guns.
We understand the legal and practical issues involved in shipping this category overseas.
Today, Lunarcat is about one of the only proxy in Japan that supports airsoft orders internationally.
