    I have an old Weaver K14 scope that has some sentimental value...I wnet to buy some scope rings at a local sporting goods store....the salesman told me that the scope was starting to fog...it looks clear to me...but I am no expert I am more of a handgunner than a rifle guy...so what does this mean to me...if it becomes a problem can it be repaired...thanks

    Fog Eliminator

    Hi. I do a lot of water/fire damaged guns and scopes and here's what has worked for me with fogged scopes...I unscrew the eyepiece end of the scope until I find a small hole at the top. This is the nitrogen filling port. I have a small can of nitrogen ( I use Wine Preserver from Private Preserve in Napa CA) I can also use the elevation screw hole. I squirt in about 4 seconds worth of Nitrogen. This displaces the air and pretty much eliminates fogging.
    All this being said, if you can't see fogging now, don't do anything.
