Straight Pull Bolt



A straight-pull bolt is an alternative loading mechanism to the turn-bolt design in the category of bolt-action guns. It features, literally, a bolt that is pulled straight back to empty the firing chamber, then pushed back into position.

Loading
If the gun is magazine loaded, pulling back the bolt and then pushing back into position is all that is required to load the gun. If it is single shot, the gun must be loaded manually each time a shot is fired by placing the bullet into the chamber when the bolt is pulled back.

Battlefield 3
In Battlefield 3, the Straight-Pull Bolt is an attachment for an unreleased amount of guns, presumably sniper rifles.
