Found this on the web...
When the o-ring on my bottle has had it's day, i can't get the bottle to seal on the gun. Try a new o-ring and put a smear of engine oil around it(both sides) and push it down against the collar of the bottle. Once you start screwing the bottle on don't stop or turn the opposite way, just keep going till it's done up. If the o-ring is not lubricated it tends to stick to the bottle or inlet and stretches and then gets pinched causing it not to seal.
A friend had a similar issue and I'm sure he just hadn't tightened the bottle enough.

The MFR has a different valve to the Rapid mk2, so you can unscrew the bottle without burping it. if you take the Bottle off then look down into the regulator, you will see a small o ring on there, that is normally the one to give trouble, change that and the one on the bottle and that should sort it. O ring kits are available from Bagnall and Kirkwoods
Use a toothpick to remove o ring don't be tempted to do it with a metal pick, otherwise it will leak forever.

Thanks kevgun, have deduced as am thick, that air is leaking loudly from small hole on regulator close to block, also (eeekk) have never seen a o ring on bottle since owning it but could have lost it. Duh. Thanks for info on rings from bagnalls as just up road.
Thanks kevgun, do I need o ring for bottle or live without?
