Fine guns when the fill valves don't leak.
New fill valves needed at each fill at £10 per fill. This is a common problem with the S310
I have 177 and 22 versions and currently wish I had not bought them.
The problem is with Air Arms at present and I expect them to come up with a solution as they have a good reputation.
