Complete your military aviation collection or restoration project with this New Old Stock (NOS) 40mm M129 Trunnion Housing Assembly / Ammunition Roller, part number 11014620 and Federal Stock Number 1010-866-9413. Engineered for the advanced M129 grenade launcher, this trunnion housing assembly and ammunition roller played a crucial role in the smooth operation and precise alignment of the launcher.

Key Features:
- Essential M129 Component: This trunnion housing assembly and ammunition roller was vital to the M129 launcher’s firing stability and ammunition feed efficiency, enabling seamless operation and accuracy. Widely deployed on the AH-1 Cobra helicopter series—including the AH-1G, AH-1Q, MOD AH-1S, and production AH-1S—the M129 provided high-rate support fire, making it an indispensable part of close air support missions.
- Historical Importance: The M129 was used extensively in Cold War-era combat operations, mounted on the M28 series armament subsystem for the AH-1 Cobra and the XM51 subsystem on the AH-56 Cheyenne. These systems brought enhanced firepower and precision to U.S. forces, ensuring the launcher’s success in tactical environments and establishing it as a reliable asset in modern rotary-wing combat.
- New Old Stock Condition: This trunnion housing assembly is preserved in its original, unused condition, retaining historical authenticity and offering collectors a pristine component for display or restoration. Its NOS status makes it a valuable addition to collections and restoration efforts focused on military aviation technology.
