The bolt is in the closed (forward) position when the weapon fires, as opposed to an open bolt, in which the bolt is in the open (rearward) position when the weapon fires. Rifles are typically closed bolt weapons, whereas belt fed machine guns usually fire from the open bolt (one exception to this is the belt fed machine guns based on the HK91/93 platform, such as the HK11 and HK21).
