This is a new old stock 20mm XM27 Powered Cupola Ammunition Lubricator Cylinder Assembly Handle, manufactured for use in the XM27 turret system, an advanced powered cupola developed for U.S. armored vehicles during the Cold War era. Identified by Part Number 11619449 and FSN 1005-052-3765, this handle was a component of the ammunition lubrication system that helped ensure reliable feeding and firing in 20mm automatic weapon systems—particularly in high-rate-of-fire configurations where friction and fouling posed serious mechanical risks.
The XM27 powered cupola system was designed as a remote-control turret mount to enhance the firepower and survivability of armored personnel carriers like the M114. It typically housed a 20mm M139 autocannon (based on the Swiss Hispano-Suiza HS.820), and systems like the lubrication cylinder were essential in maintaining the cyclic function of the gun during extended bursts. The handle provided mechanical control or service access to the lubrication assembly.

Historical Significance:
The XM27 was part of a modernization push during the 1960s and 1970s to replace manually operated machine gun mounts with stabilized, powered turrets offering enhanced protection and firepower. Though limited in production, the XM27 and its associated systems played an important role in bridging the gap between WWII-era turret technology and the remote weapon stations of today.
