Abstract
An ammunition magazine for beltless fed ammunition is disclosed. The magazine includes at least one endlessly guided ammunition guide chain to transport ammunition, and a chain tightener to tighten the ammunition guide chain with a predetermined chain tension. The chain tightener carries out a clamping movement in the direction of tightening to increase the chain tension and carries out a clamping movement against the direction of tightening to reduce the chain tension. To prevent slack from developing, (for example, during acceleration of the ammunition guide chain), the chain tightener is provided with a brake to influence the spring constant of the chain tightener as a function of the direction of tightening and the speed of the clamping movement.
