I'm a lefty and one can adapt, especially if they start young. I agree that eye dominance is key. As it turns out, I'm right eye dominant and no one noticed. It would have been much easier if someone had taught me to shoot with my dominant eye.
Another possibility is a modified military gun from around WWI-WWII that has the old straight bolt (I recommend a Mauser). A lefty can manage these. A scout scope can be used for optics, mounted on the rear sight base, or install a peep sight (look at Williams, Lyman or Mojo sights).
