Straight-pull rifles differ from conventional
bolt-action mechanisms in that the manipulation required from the user in order to chamber and extract a cartridge predominantly consists of a linear motion only, as opposed to a traditional turn-bolt action where the user has to manually rotate the bolt for chambering and
primary extraction. A straight-pull mechanism is also distinct from
lever action and
pump action mechanisms. 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 speed. The action lever is located close to the trigger, and is accessed by slightly moving the index finger off the trigger. Pulling the lever rearwards ejects the spent casing. The bolt is then pushed forward using the thumb, upon which the firing hand lands naturally in the pistol grip so that the shooter is ready to fire immediately after completing the cycling.
