The 44M "Buzogányvető" Páncéltörő Rakéta (English: Anti-Tank Rocket System Model 1944 "Mace Thrower") was an unguided anti-tank rocket designed in Hungary for use against Soviet heavy tanks and infantry during World War II. It was also known as the "Szálasi-röppentyű" (röppentyű is an archaic word for artillery rockets).

In 1942, the Haditechnikai Intézet or "Institute of Military Technology" began work to develop a cheap and easy to produce weapon capable of destroying Soviet heavy tanks after Nazi Germany was unwilling to share technology related to their work on an experimental wire-guided missile.

The first prototype was completed in the spring of 1944 and underwent testing in the military camp of Esztergom. After recommendations from troops who tested the weapon were taken into account, it was approved for production in the summer of 1944.

There was also German interest in the development. The Waffenamt received on request from its director, General Emil Leeb, several samples of the weapon.

Mass production started in the summer of 1944 at the steel pipe factory of the Weiss Manfréd Company, where Chief Engineer Magasházi led production. After complaints were made by soldiers who tested the weapon relating to the experimental tripod the weapon was mounted on limiting maneuverability, production of the tripod was cancelled. Hungary, however, lacked the industrial capability at the time to manufacture a brand-new mount for the weapon. Due to this, captured wheeled mounts were used instead, mainly "Sokolov mounts" from captured Maxim M1910 and SG-43 Goryunov machine guns, as Hungarian forces had captured many of these mounts during the duration of the war.

Production of the weapon continued even as the Soviet Invasion of Hungary began, this was until Soviet Troops reached the city the factory resided in and fighting over the city began. Sources conflict as to whether the factory was destroyed or captured by Soviet forces on 20 December 1944, but either way production was halted entirely, and never resumed. During the time of production 600 to 700 units of this weapon were produced

The weapon consisted of two launch tubes mounted on either a captured Maxim M1910 or SG-43 Goryunov machine gun mount. A large, thin metal shield separated the firing mechanism of the weapon from the launch tubes in order to protect the gunner from the back-blast of the weapon's initial propulsion charge. The gun used a machine gun sight to aim and had two paddle like triggers on the bar-like hand holds the gunner would hold on to while aiming the weapon.

The crew consisted of three men, a single gunner and two loaders.
