mark 4 4.5-14x50 illuminated TMR
My good friend has the above scope and is considering selling it. its a couple of years old and has been in the field hunting/shooting approx 10 times. He recently bought a 338 edge with a nightforce, so he is looking to sale this scope. He wants to get a fair price.
so, from the guys in the know, what would a fair price be?
