I was delighted to see IMADMAN's post re his airsoft gun. I've been having the same problems tracing some similar items, especially ammunition for them.
The items I'm trying to trace are the K K Matsushiro Air Sport SS Super 5 and a W7000 (Winchester style rifle) which is similar to the SS Super 7.
I've also got the Super Colt.
Taking a tip from the previous posts I've uploaded some images to Photobucket.
These are the links,
Can anyone in your group suggest where to go for cartridges/ammo?
I'm prepared to do a deal on the W7000 rifle if I can get cartridges for the other two. Depending on how much ammo etc I can get I'd even consider a swop.
