Cambodia. There's a couple of shooting ranges just outside of Phnom Penh, the capital. They're technically illegal, but the government turns a blind eye because they're such a good money spinner...

I had a hoon on an unadulterated ex-Khmer Rouge AK47 in January when I was in Asia. They're so goddamn fun.

Was also offered the chance to shoot an RPG at a cow for $400usd. Or throw a grenade...
