I'm kind of new to these spiffy Picatinny (I guess that's what it is) rails & red dot sights. The battery's dead on it, but I'm hesitating to replace it. To change out the battery, I have to take the whole deal off the rail. If I put it on in the exact same spot, will I have to resight it, or does it retain its settings?
