M129 40mm Grenade Launcher
The M129 was a redesign of the M75 grenade launcher that featured a concentric cam that reduced recoil and improved mounting. The M129 had an improved rate of fire of up to 400 spm. The M129 was used with the chin-mounting M28 series armament subsystem used on the AH-1G, MOD AH-1S, and Production AH-1S Cobras. The M129 was also used on the AH-56A Cheyenne on the XM51, and the UH-1H "Huey" on the XM94. The M129 was also used on the OH-6A Cayuse and OH-58 Kiowa light observation helicopters on the XM8. The M129 was classified Standard A (over 1,667 units were built).
