Well done on your gun. I've had one for a while now and think it's a very good rifle.
Very accurate and consistent.
Make sure you get a chrono and check it regularly. Combro Chronos are good and can be linked to your computer.
Be careful when you fire the gun from a rested position not to support the weight too far along the ali shroud. Some people have found it flexes and pushes the barrel up and moves your poi.
Might be worth taking the shroud off and have a look just above the reg to see if it has anti tamper fitted.
There should be an Allen headed grub screw sticking out if it's not fitted.
Paul Rendell at bisley can get spares if you need them.
Warren Edwards on here makes excellent replacement wood parts for a really good price.
Walther cylinders fit it, I've got a few as it's easy to carry a few cylinders rather tgan lug a bottle around. The ali ones lighten the gun a bit too.
