Not shock proof - Bushnell Trophy 1x28 Rifle scope Matte 4 Dial-In Electronic - Green Dot for low light, Red Dot sight for bright light 730135

Bought this optic for it is for pistols and shotguns. I place it on my Ruger Redhawk 44 magnum, set the dot with my 44 laser bullet, took it to the range to set the range. second shot the dot was knocked off, the 5th shot it shattered the front glass, was very suprised. Now need to go thru the hassle of replacing it
