If you're going to regulate an Air Arms then you've got to do it right so you've got the best out of it or not bother. That means spending a fair bit of your time setting everything up bob on or spending a fair bit of money for someone else to do it. Robert Lane has a separate download document for just Air Arms regulators on his site. Worth reading as it would apply to any make being fitted...He reckons he'd charge £195 just to set it up.
