Thats bloody cheap, well done! It'll be the 25mm comp tube to no doubt which should make it even sweeter to shoot
The 97 stock fits like a glove with the higher cheekpiece but lacks the elegance and classic lines of the 77 standard stock. Yours look a beaut. Are you in the lowest possible mounts? I went with a 40mm scope for that reason. Personally, with a springer especially, I don't feel you need much more - just buy quality glass.
