Toy guns have come a long way from the days of Nerf. This one, the Airsoft Submachine Gun featured on ThinkGeek, is about as far from those neon-green pistols as they get. It has freaking LASER SIGHT. And an illuminator flashlight built in. And it's so awesome, it comes with protective goggles. Not to mention the fact that it actually looks like a legitimate weapon, rather than something out of "The Jetsons."
If you're one of those types who's so hardcore that you play paintball in tanks, then yeah, maybe you'll like this. Just don't take it on a plane with you, unless you're psyched to get on the no-fly list.
