the blue book is old news the day it is published. the pricing data is at least a year old. the real value of the blue book is the technical data and specifications it contains. and as the publisher points out, it is only a guide to firearms values.

if you want real time values, do an advanced search on gunbroker and gunauction for auctions completed in the last 90 days. that will give you much more current valuations than any printed matter. in addition, many live and on line auction companies publish sold for values on their web sites. amoskeag, julia and rock island are among the most comprehensive.

keep it simple and keep it safe...
