The transmission element is preferably pivotable about an axis and connected to the trigger blade via a joint such that the front end of the transmission element is raised by pulling the trigger blade. The transmission element can be connected to the trigger mechanism arranged in the action box via a connecting pin that is axially displaceable in the trigger housing.

[0010] The front connection area of ​​the buttstock is preferably adapted to the shape of a pin on the rear of the action box and has an inner shape corresponding to the outer shape of the pin. This allows for a precise and reproducible connection between the buttstock and the action box.

[0011] The buttstock can be constructed in one or more parts. In a multi-part design, the buttstock can have an extension piece that can be attached to the rear of the receiver and a shoulder rest that is adjustable relative to the extension piece. The shoulder rest can be slidably guided on a guide piece arranged on the extension piece.

[0012] The trigger unit with the trigger blade and the transmission element can expediently be arranged on the extension piece. A grip piece, e.g., designed as a pistol grip, can also be attached to the extension piece.
