Hello, I have a variety of sights and a variety of guns I use them on, which range from an Aimpoint, to an EoTech, to a typical NC-Star red dot, to iron sights (all replicas). So, my question today is, is it worth the extra money to buy the ACOG with a doctor sight? Do those who have it find themselves using it often, or forgetting to use it? Any suggestions when it comes to ACOG replicas will be greatly appreciated due to the fact that I've never bought one before and I only plan on buying one. Thanks!
