Could someone tell me if this scope was actually made in the USA? I know it it says that on the scope but I have found with other products it doesn't always mean it was actually made here but rather that the headquarters is here. It has parallax adj up to 1000 yards. It is a very clear scope in excellent condition but I cannot rotate the power adj past 6.5. At that power it feels like it hits an internal lock and I don't want to try and force it. I would also like to know if anyone can give me an idea of its value?
