hi ive got a HW100 22 ive just discovered a little air leak comming from the end of the bottle where i screw it into my gun i have the old type bottle not the quike fill was wondering if i could just take the end bit off n replace a seal or something or do i buy a new quike fill bottle??? if i brought a quike fill bottle would i have to buy a divers tank and all the trimmings too? i use a hand pump at the moment havnt really got the money to splash out on all new gear if i can just have this bottle repaired? any help or advise would be apprecitated thanks
