The problem with all this pre 64 collection/investment stuff is that many (most) of the guys who GIS are aging or dying off.
Most young shooters are pissed they have to pay $500 for some mass-produced POS rifle, and are upset they don't get the scope for free with a lifetime warrant
Most don't know what a pre 64 is and could care less. These aren't the kind of people likely to buy Rules Book for $600-$700 bucks.
