Can't Go Wrong With American Made Leupold...
American Made Leupold Rifleman 3-9x50 (they have others in the Rifleman Series, I have the 3-9x50) its their budget scope and I read a Guns Magazine Article where they did a torture test on it; where they froze it in a block of ice, boiled it and repeated and defrosted it by running warm water over it...
Will see if I can find it online, I am paraphrasing it a little, but accurately...
No fogging, still as good as it was out of the box...
Passed all the same torture tests their high-end scopes did...
I have one of these on a Marlin 336 in 30-30 and would recommend it to anybody...
You can occasionally find these at a great price on ebay, and some walmarts carry them; ebay is usually cheaper...
Leupold's next up scope is VX-1,2,3 etc...
Again, occasionally find these at a great price on ebay, sometimes lower than the Rifleman aforementioned...
I have a several Leupold's, just the one Rifleman; but I am happy with all...
And like all Leupold Scopes they have 100% Lifetime Guarantee...
My two cents...
(-$2.00) after Obummer & Companies Taxes...
