I own about a dozen of them, the vast majority being 3X9, some 40 years old..never sent one back, never had one move, never had one misfunction or leak ever.. dollar for dollar.. they are hard to beat.. the lifetime warrenty is worthless..you never sent one back anyway, I just bought the new Ultimate Slam and out it on my Bone Collector..lovers of the Nikon BDC will be impressed with the new scope, the slightly smaller dots make it much easier aiming at long distance than that big same sized circle at all distance, take a look BEFORE you comment...that's all I ever buy and ever will.. Nuff said on that....
