I bought one recently from Marvin the air gun guy in Canada. (Marvins airgun oldies online) It's a great fun. Having the valve pinned is a necessity in my opinion. Im not convinced about bulk fill mine shoots 10 magazines on a regular co2 capsule. Message Marvin he can get most things. Be prepared to pay customs duty was £30 in my case but his prices are very reasonable so it wasn't a problem for me & he is fully used to shipping to the UK.
