Not argueing, just trying to understand your procedure. I lap (at least lightly) ALL my rings.
I find that if you buy quality rings and bases they do not need laping if you have perfict
alignment before you place the scope in the rings and are carefull not to over tighten.
If you cross tighten the ring screws to prevent rolling the rings on the scope they won't
mark the scope.(I have never marked a scope using this method.)
However, If you have a set of rings that will not line up then lapping will be nessary to
keep from marking the scope.
As to alignment , I made my own scope allignment tools because I was not happy with
the ones available . All I did was take aluminum round stock and turn it to the proper
dia. for each scope tube .(30mm=29.98 and 1''=.998 ) 12'' long) this allows me to tweek
the rings or determine if they are good enough to use .
If I can't get this tool to slip through both rings then they are rejected.
My main concern with laping the rings is that you can easly over do it and then you will have
trouble holding the scope.(I have heard of this on many occasions even on this web site.)
Of corse if the person knows what he is doing this should not happen.
The last time I used a set of rail mounts (A good brand name) They were so far off that they
would have damaged the scope if used as they were and so bad they could not be saved
even by lapping.( They were over $150.oo and were promptly sent back and the maker was
very appreciative and called back later and told me what was wrong and how sorry he was
for letting them get out of his shop.
I may be to fussy but you should'nt have to lap rings to make them fit.
I'm not against lapping it's just that if you have to lap a set of rings to keep them from
damaging the scope I don't need them !!!!!
An the other problem with lapping is that while you get the rings to fit the scope it may not help
allign the scope causing an excessive amount of windage or elevation adjustment.
You may disagree but I don't like fixing other peoples screw ups.
