The Deactivated Weapons Association or DWA is a UK non-profit organisation with the aim of providing support and guidance to all of those involved in the supply, retail and collection of legally deactivated firearms.
Established in 2014, the DWA was setup as a trade-only organisation and has an elected governing body with representation across the trade from importation, through deactivation to retail. All members of the governing body are unpaid volunteers. In 2019 launched a membership option for living history, reenactment and military vehicle preservation groups and societies.
The DWA is a member of the BSSC (British Sports Shooting Council) and is now recognised by the Home Office and other UK authorities as the primary organisation representing the interests of deactivated firearms in the UK.
