i currently own a webly raider 10. i came to use it last week, after not having used it for a while, and found that the air pressure had completley disapeared. i know that the last time i used it, i left with about 150 bar in the tank. its been a few weeks since id used it. i took it to the local gun shop to get some wind put in, cos i dont own a divers bottle myself. anyway long story short. the guy tried to fill it and he said the air was blowing straight through the back of the rifle. he said it was probably be the seals, and he would need to send it to webley to have the seals redone, at a cost of £70-£80. was just wondering if any other owners had come across this problem, and if there was any info available that would enable me to have a go @ replacing these seals myself? also does this price seem ok for the job to be done.
