This original U.S. military surplus 20mm XM27 Powered Cupola Yoke Mounting Bracket is a rare and essential component designed for the XM27 turret system used on armored fighting vehicles during the Cold War. Identified by Part Number 23173 and Federal Stock Number (FSN) 1005-867-5375, this bracket was engineered to secure the yoke assembly that interfaced with the XM27's powered cupola and weapon mount system—typically for a 20mm M139 autocannon.
The XM27-powered cupola represented a transitional design in the evolution of remote and power-assisted weapon stations during the 1960s and 1970s. Developed to give armored vehicle crews enhanced fire control while remaining protected within the vehicle's hull, the system featured powered traverse, elevation, and integrated optics. It was tested on a number of tracked vehicle platforms, including various M114 variants and early concept vehicles that led to future systems such as the M2 Bradley.
