I have a Redfield 6400 16x that is sitting at L K Scope repair, the owner told me someone had replaced the front objective lens with one from a 3200 16x. I was wondering if anyone out here might know where I could get a lens for this particular scope, or a parts scope for that matter. Any help would be appreciated to say the least, already have 450.00 into this one that does not work. Thanks for looking.
