ABSTRACT:
A muzzle brake (10) for a gun barrel (12) to be attached coaxially onto the muzzle end of the gun barrel up to a radially extending annular abutment surface (20) and provided with elongated gas discharge openings (14) which are arranged transversely to the axis of the bore (16) over its lateral effective length region (L.sub.2) and have a minimum opening length (L.sub.1) at the rear of the effective length of the muzzle brake (10), i.e., adjacent the position of the abutment surface (20), the axial inner bore (18) of the muzzle brake (10) has an inner diameter (d) which corresponds to the rifling diameter (d.sub.1) of the gun barrel (12) and its rear end ends at the radially extending abutment surface. The gas discharge openings (14) are provided with rearwardly sloped baffles (24) and gas guide surfaces (26) which have different lengths in the rear region of the muzzle brake (10) and have the same opening length (L.sub.1) in the forward region. The rear end of the muzzle brake (10) where it encloses the gun barrel (12) is connected with the gun barrel (12) by a separate tensioning device (22) and can be given a defined pretension. The tensioning device (22) exerts a high tractive force on the rear end of the muzzle brake (10) so that the abutment surface (20) lies sealingly pressed against the end surface (38) of the gun barrel muzzle.
