The protagonist was alluding to the Anarchist Cookbook, anyone else noticed this?
"I say, it sounds like some dangerous psychotic killer wrote this, and this buttoned-down schizophrenic could probably go over the edge at any moment in the working day and stalk from office to office with an Armalite AR-180 carbine gas-operated semiautomatic."
"Maybe, I say, this totally diseased fuck would use an Eagle Apache carbine because an Apache takes a thirty-shot mag and only weighs nine pounds. The Armalite only takes a five-round magazine. With thirty shots, our totally fucked hero could go the length of mahogany row and take out every vice president with a cartridge left over for each director."
"The J and R 68 semiautomatic carbine also takes a thirty-shot mag, and it only weighs seven pounds."
That's straight out of the Cookbook, remembered somewhat while I was reading it. Page 95 from http://preterhuman.net/texts/terrorism_and_pyrotechnics/explosives/MISC/... Going to re-read Fight Club to see what connections can be made.
