In the M129 the barrel is concentric with the drum and the excessive torque is thus eliminated. Otherwise, operation of the weapon is extremely similar to that of the M75, with the reciprocating barrel and cam assembly still presenting itself, the weapon still being electrically driven and ammunition still fed through a belt system. The M129, like the M75, is an air-cooled, electrically-powered, cam-driven automatic grenade launcher. It was developed from the earlier M75 and was capable of using both the high-velocity 40x53mm grenade and the lower velocity 40x46mm grenade. It was developed from the earlier M75 and was capable of using both the high-velocity 40x53mm grenade and the lower velocity 40x46mm grenade. [3] The major problem with the M75 was the torque created due to the barrel being below the operating drum. It also boasts a dynamic braking system which ensures that the barrel always stopped in the forward (safe) position when the firing trigger is released. This weapon significantly increased the firepower of aircraft, but had characteristic disadvantages. The M129 was effectively a redesign of the older M75 to incorporate a concentric cam and improved mount.

Die M129 war effektiv ein Redesign des älteren M75 einen konzentrischen Nocken und verbesserte Halterung einzubauen. Some other improvements were made to the M129, most notably that of the addition of special feed tray to permit the firing of low-velocity and high-velocity ammunition, a mechanism to provide instant interchange between electric operation and manual hand-crank operation and a dynamic braking unit to guarantee that the launcher barrel always stopped in the forward (safe) position when the firing trigger is released.
