The definition of Preservation is to stop is from decaying or something being eroded. There are instances where BF for example have tried to confiscate RIF's even with a valid Defense. UKAPU has managed to prevent that from happening. It happened to one other lad, whilst they weren't able to get the RIF's back, he did get a full refund.
Keeping up to date on the relevant legislation but also how government bodies apply that is not exactly easy. UKAPU have recently discovered that BF have started testing RIFs for joule rating and have seized goods to that effect where they didn't before.
Also discovered is that the new Firearms Act 2023 bill that is in progress could affect the way we use Primers and blank rounds. This is being monitored.
UKAPU monitor press articles that mention airsoft and contacted editors and to acquire redactions. (One example being the Plymouth shooting back in 2021)
UKAPU contacts the home office when in need for clarification of the VCRA.
The HO took UKAPU's, Tim from ATB and UKARA concerns into account and put an exemption into an amendment through to the House of Lords back in 2016.
UKAPU have attended meetings with the EAF to foster an shared rules and values between other European Airsofting countries. This could set the groundwork for legitimisation of Airsoft.
During the pandemic UKAPU were in contact with the Department for Digital, Culture, Media and Sport in regards to whether Airsoft could be considered for reopening during lockdowns whereas paintball was able to.
I am sure there are many other things that I am not aware about that UKAPU have done.
I would also say at the moment there are no threats to Airsoft as a whole. However this could change with one politicised incident. But if you have an organisation that is on the look out for those threats and ready to jump in, that would be far better than something that is formed ad-hoc. Having UKAPU ready to defend Airsoft at a moments notice (With the funds to back it up), is better than a ragtag group of Airsofter's with no funds only being able to respond reactively.
I would suggest the UKAPU is the best and most experienced group to defend Airsoft from a legal position.
