Arrangement for opening the dust flap of a firearm

摘要

An apparatus is provided for use in a firearm having a housing defining a first ejection opening and a second ejection opening. The apparatus includes first and second dust flaps mounted adjacent the first ejection opening for movement between an opened position and a closed position. The apparatus also includes a bolt assembly adapted to be selectively mounted in a first assembly position and a second assembly position for longitudinal movement within the housing. When the bolt assembly is in the first assembly position, a longitudinal movement of the bolt assembly moves the first dust flap to the opened position and, when the bolt assembly is in the second assembly position, the longitudinal movement of the bolt assembly moves the second dust flap to the opened position.
