chasseur,

...i spoke to both jj (champlin) and mark (necg) at the recent sci convention in reno...both seem quite competent insofar as attaching claw/eaw mounts on a double...

...i have an o/u with a very thin top-rib, which, presumably, would be required to be 'cut out' in order to attach the scope mount...

...would this be advisable (the rifle is .05 moa at 60 metres with the fixed sights)?...would jj (trained in claw mounts and barrel regulation) or mark be the preferred gunsmith for this particular procedure?...

...thanks for your thoughts...
