I have wanted a Rail Gun ever since I saw one in Quake. That being said I didn’t expect that it would weigh twenty pounds or be less powerful than a 22LR either.
The GR-1 Anvil Gauss rifle is made by Arcflash Labs, LLC, the co-founder of which, David Wirth and Jason Murray, are “Aerospace Engineers, former US Air Force officers, and experts in pulsed power supply development with 20 years of combined experience,” according to its website. The company says the weapon is “capable of accelerating any ferromagnetic projectile (under 1/2″ in diameter) to 200+ fps [feet per second]” and can produce up to 100 Joules of force, or 75 foot-pounds, similar to the muzzle energy of some .22 rifles, making it the “most powerful coilgun ever sold to the public, and also (very likely) the most powerful handheld coilgun ever built.”
