I understand the working vs. collecting argument(s) and the many different view points on the subject(s). I personally don't hesitate to use any I own and "take care" of. Still it is a shame to take an unspoiled gun and mess with it, there are lots of already messed with rifles out there to play with, some quite well done by experts. If you own a gun and you "really" like it "take care" of it as it is you may not be happy, after making changes to it - that's the dilemma, been there done that. --- John 303.
