Also because of this one must really press hard against the cheekpiece to align rearsight to the front.

What could be the possible cause for the barrel being off at an angle? Shoddy Webley workmanship? As above - it is straight, and looks to be nicely fitted into the cylinder forward block.
The barrel of the Osprey screws into the block and is threadlocked in place.
This is a weak spot, as I had one with a broken barrel just at the point where the thread ends and the barrel begins, and I know of several others that had the same problem.
Is it possible your barrel has a similar problem, with a slight crack at the weak point ? This would possibly explain why the barrel appears out of true.
