The problem its a clone. and more then likely made in china. I believe that NCstar was the first company to come out with this model. I have a TruGlo version on my GSG-5. For plinking its good. Other then that, your probably boned if you ever drop it while its on a weapon. Mine has held zero on a .22lr, but I had a problem with it one time where a small rock got caught into the elevation spring they changed my zero by 5 inches. I had to take the whole damn thing apart, which by the way is not easy. the screws stripped etc, I had to Super glue a piece of it to close it off :P. Once the thing dies, I'll replace it.



Heres a little fun sight for you
