Sometimes soldiers want to hide or muzzle the flash from their guns, but the MuzzleShot, a tactical shot glass, is clearly meant to be seen. Based on the flash hider for the M16A2 family of weapons, this unique booze holder is made from a single block of billet heat-treated aluminum. It’s all made in the USA, and hey, if North Korea’s leaders should get silly, you’ll at least have a glass that’s ready for double duty.
