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 it 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.

Trivia

 * Bolt action loading mechanisms, in real life, are significantly more accurate than semi-automatic mechanisms. This is because they do not use recoil force to load the gun, upon firing, more of the gases in the chamber propel the bullet, and so has the bullet has more inertia.
 * Bolt action designs are also more durable, as they have less parts than an auto-loader, just the pin and the spring.
 * Stealthy soldiers may use bolt action designs instead of auto-loaders because the cartridge case is not flung into the air upon firing, revealing their position. They can also prolong reloading until it is tactically feasible.
 * Straight-pull bolts take half the time to reload than a turn-bolt, because they only take 2 movements to operate instead of 4.
