I have a winchester model 94AE XTR 307 cal. and i am having trouble finding out info on it. The ser# is AE 17933 and i would like to know when it was made and if it is a big bore or not. I am trying to find scope mounts but the front mount made by wever has inline screw holes and mine are side by side like the rear mount. Please help me fine some info on my gun.
