Hair trigger, I think you may be right as I have had that exact problem with 2 Leupolds, 1 Pentax, 2 Burris and a Nikon. I had never had a Barska scope and I thought I would try one to see how it would hold up.
I just had, what you talking about happen to me. I had about 3 years ago put on a cheap NC Star pistol scope on my S&W 44 Mag. I think the scope cost me maybe $50 and after 3 years and about maybe 800 rounds, that cheap NC Star broke on me yesterday. Since I had taken 6 hogs and 3 deer with that scope and gun combo, I am having a tough time deciding, do I spend another $50 for a cheap scope and hope to get 2-3 years or do I spend $250 for a Leupold. The one thing that I keep in mind is on the cheaper scopes, when it screws up I will just throw it away. And when a Leupold messes up I will have to send it off to get repaired because of the cost of the scope. Only problem is last time Leupold took 9 weeks to return my scope. But again I agree with you about the cheaper scopes
