Action

This firearm features a unique loading port on the left side of the receiver.[5] As the first round is loaded, the shell is lifted by a mechanism and chambered by the bolt; once the bolt is closed, the lifting mechanism returns to the resting position below the loading port, where the next round can then be loaded. Upon firing the chambered round, the shell in the loading port is automatically chambered. The total capacity is 2 with 1 chambered round and 1 in the loading port.
