Hey Guys, I got in to Airsoft a few months ago and really want to get the WE Desert Eagle in silver, with the rails. Being based in the UK, I can't find any in stock in any online stores. Only the version without the rails seems to be available, although in very limited quantities an pretty hefty price tag. Do you have any ideas where I could order the WE Desert Eagle with the rails? Photo attached. Any advice would be appreciated!
