You will need a new safety as the stock safety will hit the underside of you scope. I've sourced replacement safety levers, but US Import laws prevent me from getting them. A royal pain in the behind, as I can't seem to find a source for them in Canada.
You can get a trigger assembly with a safety lever attached; but its not quite the same. My Swedish mauser was bubba'd a long time ago, so not a problem for sportarizing. I used Redfield junior bases, solid like a rock. Gunsmith told me the steel was the hardest he'd drilled.
