    Mainspring on a bolt-action rifle (marked with C) In firearms , the mainspring is a spring in the firing mechanism which stores the energy required to ignite the primer of the cartridge . [ 1 ] The mainspring may be called a striker spring [ 2 ] on striker-fired firearms, or hammer spring [ 3 ] on hammer-fired firearms.

  4. Recoil buffer - Wikipedia

    en.wikipedia.org/wiki/Recoil_buffer

    The simplest form of recoil buffer is made from a resilient and deformable material (leather, rubber, polymer e.g. a rubber butt pad on a shotgun). [1] A second way of producing a recoil buffer is to insert a spring into the recoil train—the path/part(s) generating recoil impulse.

  5. Muzzle brake - Wikipedia

    en.wikipedia.org/wiki/Muzzle_brake

    A muzzle brake or recoil compensator is a device connected to, or a feature integral (ported barrel) to the construction of, the muzzle or barrel of a firearm or cannon that is intended to redirect a portion of propellant gases to counter recoil and unwanted muzzle rise. [1]

    en.wikipedia.org/wiki/Muzzle_booster

    Animation of the Vickers muzzle booster operation, showing the expanding gases pushing the barrel to the rear relative to the cooling jacket. A Vickers-type muzzle (or recoil) booster, the "typical" type, consists of two parts: a flared "cup" on the muzzle of the barrel, and a perforated tube around the end of the muzzle, attached to the main body of the weapon.

  7. Hydraulic recoil mechanism - Wikipedia

    en.wikipedia.org/wiki/Hydraulic_recoil_mechanism

    The usual recoil system in modern quick-firing guns is the hydro-pneumatic recoil system. In this system, the barrel is mounted on rails on which it can recoil to the rear, and the recoil is taken up by a cylinder which is similar in operation to an automotive gas-charged shock absorber , and is commonly visible as a cylinder mounted parallel ...

  8. Beretta Cx4 Storm - Wikipedia

    en.wikipedia.org/wiki/Beretta_Cx4_Storm

    The Beretta Cx4 Storm is a pistol-calibre semi-automatic carbine aimed at the sporting, personal defense and law enforcement markets. It was designed to accept magazines from different Beretta pistol platforms ( 92/96 , 8000 "Cougar" series , Px4 ) using adapters.

  9. Locked breech - Wikipedia

    en.wikipedia.org/wiki/Locked_breech

    Firearms that are physically small, such as handguns, use a system of recoil referred to as short recoil. [1] [4] This is adequate for the smaller calibers. In large firearms such as the Browning M2HB .50 caliber machine gun a similar system called long recoil is used. The difference is how far the breech and barrel recoil together after a shot ...
