Lighting a BBQ can be done with a match. But, as any NRA member can attest, it's a job best left to a gun.
The Shoot and Cook Rifle BBQ Lighter is a 36cm implement that can set pretty much any flammable material on fire. Sure, it's designed to light coals on a grill, but I can think of plenty of uses for a flame-inducing side arm.
Imagine, you're at a bar. A lady needs a light. You reach into your pocket and pull out the Shoot and Cook Rifle BBQ Lighter. She says, "Oh no he's got a gun!!" Bouncers rush toward you. They can't tell if the tiny rifle is real, but these guys aren't taking any chances.
