If these things are so dangerous, why is the government selling them to surplus dealers?
There is no cooler place on Earth than a good surplus shop!
Don't I know it! I wish I could find one. When I was a kid Sunny's Surplus had it ALL. You could get ANYTHING, up to a functional M3 halftrack or M4 tank chassis. When my buddies and I played war we looked like the gen-yoo-wine 101st Airborne...every peice of gear was authentic or nearly so. We even had dummy Springfield drill rifles. My buddies dad made him a whole bandolier full of inert .30-06 rounds on strippers so he could actually pretend to load his gun. Even better, back then you could get Axis relics for next-to-nothng at flea markets, so our "enemies" were fairly authentic, too. One kid had a real M38 tunic complete with an Iron Cross First Class. You could buy a really nice gun for what it'd be worth today, but he played in it until it went to bits.
Kids today have no idea how cool things used to be.
