If you contact JD Airsoft (Phil) or Badger Tac (Ian) in the UK, they have them available for sale.
These 2 dealers have been appointed the UK retailers by the new UK & Irish Distributor; a company called Specialist Tactical Training Solutions and they come with a 12 month warranty backed in the UK by the distributor with all parts available from stock.
They have them prices at £649.99 but as I mentioned they are the only shops that offer the CTW with a warranty.
They also have all the magazines, batteries, Upgrade kits, Vanaras Magazines and 6.03mm barrels if youi want them as well.
Let us know how you get on.
