For some reason I didn't even know it was available as an ebook until I read this. At which point I promptly bought it. Dead trees and their lack of Ctrl-F... :)
To be fair, the physical book comes with access to the ebook.But the reason for me to buy the ebook was simpler -- it's half the price :)
Still lack time to read it, but I like the AK47 tip (don't have one, but I'm sure it works for most rifles)!
