Silencer (firearms)A silencer, also known as a sound suppressor, suppressor, or sound moderator, is a muzzle device that suppresses the blast created when a gun (firearm or airgun) is discharged, therefore reducing the acoustic intensity of the muzzle report (sound of a gunshot) and jump, by modulating the speed and pressure of the propellant gas released from the muzzle. Like other muzzle devices, a silencer can be a detachable accessory mounted to the muzzle, or an integral part of the barrel.
Rifle grenadeA rifle grenade is a grenade that uses a rifle-based launcher to permit a longer effective range than would be possible if the grenade were thrown by hand. The practice of projecting grenades with rifle-mounted launchers was first widely used during World War I and World War II and continues to the present, with the term "rifle grenade" now encompassing many different types of payloads including high explosive, fragmentation, anti-tank warheads, concussion, smoke, incendiary, and flare missiles.
Personal defense weaponPersonal defense weapons (PDWs) are a class of compact, magazine-fed, submachine gun-like firearms designed to fire rifle-like cartridges. Most PDWs fire a small-caliber (generally less than in diameter), high-velocity centerfire bottleneck cartridge resembling a scaled-down intermediate rifle cartridge, essentially making them an "in-between" hybrid between a submachine gun and a carbine.
Lewis gunThe Lewis gun (or Lewis automatic machine gun or Lewis automatic rifle) is a First World War–era light machine gun. Designed privately in the United States though not adopted there, the design was finalised and mass-produced in the United Kingdom, and widely used by troops of the British Empire during the war. It had a distinctive barrel cooling shroud (containing a finned, aluminium breech-to-muzzle heat sink to cool the gun barrel) and top-mounted pan magazine.
Fully powered cartridgeA fully powered cartridge, also called full-power cartridge or full-size cartridge, is an umbrella term describing any rifle cartridge that emphasizes ballistic performance and single-shot accuracy, with little or no thought to its weight or recoil. They often have a caliber comparable to or greater than and a maximum effective range of at least , and are intended for engaging targets (large game animals) beyond . However, cartridges with calibers as narrow as 6.5mm have been described as full-power.
Rifle cartridgeA rifle cartridge is a firearm cartridge primarily designed and intended for use in a rifle/carbine, or machine gun. Fully powered cartridge A full-powered cartridge is a rifle cartridge used interchangeably between service rifles, sniper rifles, and general purpose machine guns. It is a retronym for rifle cartridges used prior to and during World War II. They are primarily used today in general purpose machine guns, designated marksman rifles, and sniper rifles.
