I never liked red dots ...; always (being somewhat a traditionalist) prefering a good scope well mounted. Never had any problems; top European scopes being foul-proof, are they not? Today my new Kahles ( a steel tube 2.5x) scope did something new: it blew his horizontal post at the second! shot from my 404 mauser.
At the shooting range, it's only a matter of refund, in Africa it's a bitch!
