In many animals, the structure is called a muzzle, [1] rostrum, beak or proboscis. The wet furless surface around the nostrils of the nose of many mammals is called the rhinarium (colloquially this is the "cold wet snout" of some mammals).
Muzzle may refer to: Muzzle (anatomy) or snout, the projecting parts of the face (including the nose and mouth) of an animal Muzzle (mouth guard), a device that covers an animal's snout; Muzzle (firearms), the mouth of a firearm; Muzzle (band), a band based in Seattle, Washington, U.S.
A muzzle is a device that is placed over the snout of an animal to keep them from biting or otherwise opening their mouth. Muzzles can be primarily solid, with air holes to allow the animal to breathe, or formed from a set of straps that provides better air circulation and allow the animal to drink, and in some cases, eat.
The inside of a Rheinmetall 120 mm smoothbore tank gun (seen from the muzzle) of a Leopard 2A4 Muzzle of a SIG 550 rifle, equipped with a birdcage-type flash suppressor Various types of shotgun chokes Muzzle blast modulated by an A2-style flash suppressor. The muzzle is the front end of a barrel from which the projectile will exit. [11]
A choke is a tapered constriction of a firearm barrel at its muzzle end. Chokes are most commonly seen on shotguns, but are also used on some rifles, pistols, or even airguns. [1] Notably, some .22 LR match rifles have a constricted bore diameter near the muzzle. [citation needed]
Muzzle velocity: The speed at which a projectile leaves the muzzle of the gun. Muzzle velocities range from approximately 800 ft/s (240 m/s) for some pistols and older cartridges to more than 4,000 ft/s (1,200 m/s) in modern cartridges such as the .220 Swift and .204 Ruger .

For example, if the muzzle velocity is reduced from 2,700 ft/s (820 m/s) (common for the .308 Winchester, for example) to a subsonic 950 ft/s (290 m/s), the muzzle energy is reduced by a factor of 8. Military marksmen and police units may use subsonic ammunition in suppressed rifles when minimal noise is more important than range and energy.
