Barret M-82 The Barret M-82 anti-material rifle, AKA the Barret 50 Cal, is a sniper rifle that fires bullets bigger than a standard battery faster than the speed of sound.
The weapon is easily capable of taking your head clean off from a mile away, through a solid concrete wall. Barret has an effective range of 1800 meters. And two, the sheer size and speed of the projectile gives it enough kinetic energy to literally rip apart a human being.
