Metal Gear Solid rubber band gun is non-lethal overkill
When you're caught between the lines of dueling mercenary armies, trapped in a rapidly aging body that doesn't quite react the way it used to, you need a reliable side arm to protect yourself. That was Solid Snake's situation in Metal Gear Solid 4: Guns of the Patriots, his chosen weapon the Silver Wolf pistol, recreated here in as a Japanese fan's stainless steel and rubber band DIY masterpiece. Constructed of numerous cross-drilled plates and featuring both a laser sight and integrated flashlight, the result looks to be impressively accurate and likely quite painful, as you can see for yourself in a video just below. Bonus reloading footage included!
