What's a fair market value for this scope? I have a chance to buy one that is in very good to excellent condition. Non illuminated model; mild reticle; turrets 1/4 MOA dial. I know this scope is used by some military units and only issued in small numbers. Not sure if the 42 mm objective bell is going to compromising the low light condition, but it seems quite ideal for a light weight setup. Appreciate any direct experience with this version.
