The Specna Arms SA-FX10 FLEX™ 

Series X is Specna Arms' answer to the very popular trend of AR-15-based machine pistol replicas. Thanks to its compact size and robust performance, the replica is a very good choice for CQB games. In addition, the replica can prove itself as a backup for a sniper or an RKM operator. What's more, the nylon fibre reinforcement makes the design  more durable than other polymer constructions. 

The design is equipped with a number of ergonomic features. The replica features a sliding buttstock on a sprung slide for easy disassembly, folding sights, ergonomic gun grip, enlarged reloading lever,  and front with M-LOK slots.

The model has been factory equipped with optical electronic system SA ETU ¹™. The system, based on two optical sensors, detects the position of the piston pinion and the trigger. This results in better trigger response and a full cycle with each shot, improving the life of the replica

Features of the replica:

-Small size and weight

-High ergonomics

-Front M-LOK

-Rotational Hop Up chamber

-Optical electronic system SA ETU ¹ ™ improving trigger response and replica life

To buy an airsoft weapon in the UK you must have a valid airsoft defence.

This is not a licence, it is basically just proof that you intend to buy an airsoft weapon for use in airsoft.

An airsoft defence could be a UKARA or membership with the British Airsoft Club, and various other forms of defence.

You can only obtain an airsoft defence once you are over the age of 18.

To get an airsoft defence the law is that you should play at least 3 games of airsoft, and that you must have been playing for at least two months.
You can still buy an airsoft gun without a defence, provided you are 18 or older. If you choose to do this we would, by law, two tone (paint in a bright colour) parts of your chosen weapon. This is because an airsoft gun is considered a RIF aka Realistic Imitation Firearm, because they are so close to the real steel, whereas when you paint parts of it in a bright colour it becomes an IF aka Imitation Firearm. The reason being that the bright colours make it look less realistic to the public, and therefor less likely to be mistaken as real, were it to be used for any other purpose than airsoft.

When you order a gun from us you will need to add your defence details in the comments section of the cart. If you do not have a defence you will need to write the colour that you wish to be used for two toning your airsoft weapon.

Here is what's stated in the VCRA (Violent Crime Reduction) Act:

For airsoft skirmishing, the Association of British Airsoft is putting in place arrangements to allow retailers to check that individual purchasers are members of a genuine skirmishing club or site. The key elements of these arrangements are:
1. new players must play at least 3 (three) times in a period of not less than two months before being offered membership
2. membership cards with a photograph and recognised format will be issued for production to retailers
3. A central database will be set up for retailers to cross-check a purchaser’s details
4. member’s entry on the database will be deleted if unused for 12 months.
The defence for airsoft skirmishing can apply to individual players because their purchase of realistic imitation firearms for this purpose is considered part of the “holding” of a skirmishing event.
