Others I have had the reticle spin when adjusting the power and in one case the entire windage assembly falling off in my hand while turning. Not just the knob the entire thing. I think if you don't dial for range a whole lot they seem to hold up better but if you like to dial and return to zero and use the scope as intended you will have problems eventually. I cringe every time a client brings me his rifle to tune up and he has a brand new viper he wants to mount.
