Only thing I can tell you is to make sure you have extra/spare batteries for the thing.
Found this out the hard way.[:@][:@][:@]
If the battery goes, it is such a low mounted scope I think you would be able to shoot open sights because you can see the True Glo sights thru the scope. I haven't ry it but I will to see where it hits. But you're right I will have a spare battery on hand.
