Complete redesign , I think the lenses are the same , other than that , its new . The 4x12 has a focus adjustment on the side opposite the windage adjustment , as opposed to the front lens cover . One is on my short list , Im sure Ill own one , or a pro hunter signature soon .

Ive allways been happy with my simmons scopes , I have 3 aetec's , 2 prohunters , and 2 shotgun . They are worth every penny .
