Will not hold zero - Simmons Whitetail 3-9x40mm Rifle Scope

I did not get this scope with Optics Planet, but I have now wasted my time and ammo with this scope. Had it mounted on my AR15, tight, centered and level. Bore sighted at 100 yrs and couldnt get rounds on target after 10 shots. Rechecked my bore sight and the scope was way off. Thought it could have been my mistake with adjustments. Moved to 50 yds and the scope was still off target after shooting and rechecking with boresight. Do not waste your money, ammo or time on this scope.
