SO, IF I had exchange priveleges I can order any  legal firearm available, including handguns and military appearing weapons.. In the day, anything in the catalog from my AF BX was available - including Browning shotguns, Belgium made, any gauge, or shell capacity for $125. How did an Airman being paid $19. every 2 weeks buy any?? I didn't... Always kicked myself for not having borrowed from Dad...
