After cocking,the bolt will still move freely up and down...thought replacing the o-ring P/N 25 might help- but can't remove the hammer pin P/N 20 from the 'Tube' P/N 2 in order to remove the bolt...like the hole in the tube has a burr or something. Accuracy seems to be fine, within reason... perhaps I should just 'leave well enough alone'? Very early model Disco...
Thanks,folks-

The breech to take out hammer pin? Not shure if you are doing this or not, Sorry hope this helps some. When you remove the breech screw using a clamp holding breech down to the tube helps get pressure off that darn little screw.take off barrel band remove rear breech screw. Barrel and breech come off together.I don't know if you have ever broke it down so sorry if this is common knowledge to you. If you haven't don't be scared to its easy if you need any help e mail me and ill do my best to help, if you need to call me e mail for my number. Good luck.
