When I jump into something, I research and learn all I can in order to become and effective and educated owner/operator.
There's an everything? Like most well designed pieces of equipment, the more I learn, the more I learn I need to learn.

kombayotch, have you looked at ZEDIKER's book as well by any chance? I've been wanting to order "The Complete Guide to AR-15 Accuracy" for a while now, but would like to know how much is non-overlap. My guess is that Zediker's is shooter's perspective, and "The Complete Guide to AR-15 Accuracy" is builders.
