Yeah I will do. I'll be getting a bigger air res too when I find one decently priced. Lang will be able to make the mod adaptors mate, He's told me before. It replaces the stock collar that the bean can mod screws Into so I'll keep a look out for a HW silencer now, There supposed to be quite good. I may well take you up on that offer of trying a few hammers If I'm still getting the air lock at a 200 bar fill and see If that helps at all. I havn't watched the DVD In full yet, just looked at one or 2 sections... It looks like It screws off but I need a tool that fits It.
