I suffered a sling failure and caused my Bergara Ridge to fall off my shoulder and land directly on a rock, Now the zero is off over a foot .. Is the scope trashed ? It landed on the side focus knob. I got it sighted back in but Im debating how much I trust it now. Rings look fine nothing moved crosshair is still level... Vortex Viper 4-16 x 50 HSLR
