Can you not bend the safety lever outward slightly so as not to rub the lock?
I can't stomach the safety, but on right hand guns it's out of sight, out of mind.
Were I you, I would consider three things
1) A STRONG insistance that Remington fix it right
2) An aftermarket bolt shroud that does away with the stupid safety
or, and the one I like best
3) Another manufacturers gun
The third will let Remmy know we disapprove and do it with dollars. That'll get the big green bean counters thinking, maybe, if that's possible for them.
