Fixed it for you.
It really surprises me how many people get this simple question wrong when it is asked.
to all the guys that know the correct info.
FOR THOSE WHO DONT KNOW HERE ARE SOME ANIMATIONS!!
Ok here is a animation of a regular autococker that is a CLOSED bolt
system. This means that the bolt
is closed (forward) when at rest. Watch as the trigger is pulled the bolt
is already forward, it fires, then it moves back to reload, then back forward to the rest position.
Next we have two different versions of a OPEN bolt
system, a automag and two spyder based markers. This means the bolt
is open (back) when at rest. Notice how the bolt
is back in the animations, the trigger is pulled, the bolt
goes forwards and fires, then returns back to reload at the rest position.
I hope this clears some of the confusion up...
