BELL Mount/ANM2 Pintle Adapter, allows most early US GI .30 caliber WWII BELL aircraft and ship cradles to mount on a standard vehicle socket for live fire machine gun use. This adapter uses a standard US GI Pintle, modified to accept the BELL Aircraft style pintle. A 1/4″ diameter hole must be drilled through the pintles and the supplied 1/4″ spring pin must be installed. This will prevent the machine gun from lifting off of the pintle and the socket, once locked to the socket. New Condition.
