Current weapons rely on chemical reaction to propel the projectile. This reaction results in rapid expansion of gasses which, in closed space, results in explosion. In barrel of the gun, explosion has only one exit – though the barrel itself, pushing the bullet along the way. Longer barrel allows gasses longer time to affect the projectile, thus increasing muzzle velocity and projectile’s kinetic energy. This, all other factors being equal, results in longer range and greater penetrative power for any given range, as well as greater stability which leads to better accuracy. For assault rifles, muzzle velocities range from 715 m/s (AK-47) to 960 m/s (M-16), or generally between 600 and 1 000 meters per second. Sniper rifles have similar muzzle velocities, but heavier projectiles and longer barrels. Specifically made suppressed weapons and ammunition are designed to keep muzzle velocity below the speed of sound in order to reduce the sound signature, but have to sacrifice range to do so. Overall, for the same ammunition, longer barrel means longer range and greater lethality.
