Most straight-pull rifles have a striker firing mechanism (without a hammer), [citation needed] and models using a hammer usually have a comparably longer lock time than hammer-less mechanisms. The Anschütz Fortner action used in biathlon is a good example of an ergonomical straight-pull rifle with good economy of motion and high operating ...
The Noveske Rifleworks KX-3 is a flash suppressor intended for use on shorter barreled rifles and aids in reliability. The back pressure generated through this type of flash suppressor helps to cycle the rifle. Noveske patterned this design on the muzzle brake found on the Soviet AKS-74U carbine, where it was explicitly used for this purpose.
Sear shown in a revolver action. In a firearm, the sear is the part of the trigger mechanism that holds the hammer, striker, or bolt back until the correct amount of pressure has been applied to the trigger, at which point the hammer, striker, or bolt is released to discharge the weapon.
Thus, most DA/SA guns either feature a conventional safety that prevents the hammer from accidentally dropping, or a "decocker" – a lever that safely and gently drops the hammer (i.e. decocks the gun) without fear of the gun firing. The latter is the more popular because, without a decocker, the user is forced to lower the hammer by hand onto ...

Charging handle being pulled on an M2 machine gun. The cocking handle, also known as charging handle or bolt handle, is a device on a firearm which, when manipulated, results in the bolt being pulled to the rear, putting the hammer/striker into a spring-loaded ("cocked") "ready and set" position, allowing the operator to open the breech and eject any spent/unwanted cartridge/shell from the ...
The hammer itself cannot contact a loaded cartridge, but must instead strike the transfer bar, which then contacts the cartridge primer with the spur or pin. The transfer bar is normally positioned out of line with the hammer's travel, but is moved into place by the normal action of the trigger, providing similar "drop safety" to a firing pin ...
