A valid defence is required to purchase any Airsoft Replica Firearm. If you don’t have a defence you must add Two Tone to your basket.

If you require a RIF to be painted two-tone to be VCRA compliant (No Valid Defence / Site Membership / UKARA etc) then please add TWO TONE to your order.

If you require a RIF to be painted two-tone to be VCRA compliant (No Valid Defence / Site Membership / UKARA etc) then please add TWO TONE to your order.

To purchase a realistically coloured Airsoft Replica Firearm (RIF) you must have a valid defence.  The most common of these is UKARA which stands for United Kingdom Airsoft Retailers Association and is essentially a database of registered players.  UKARA requires you must be a site member at any of the registered UK Airsoft sites.  This means you must play 3 games in MORE  than 56 Days. Once you become a member you are added to the database, please note paperwork and validation is required.  There are other types of defence, but UKARA is by far the most popular.  Please note this only applies to the gun, not the kit or accessories.

If you don’t yet have a defence, you can always add two-tone to your order. This simply means you have 51% painted in a bright colour such as green, blue or orange.  You can then purchase any RIF you wish.

If you have any questions regarding what is or isn’t a defence, or just looking for some general airsoft advice, then please drop us a call or contact us here
