These are USGI shield mounts that were used M113 during the Vietnam war and on other various vehicles. Originally set up for M2HB guns. These retain the pintal fork but the cradle is missing. They will all need some straitening and welding repairs. These need to ship truck because of the size and weight. They are also available for pick up.
You MUST call in to order as these ship freight. Order can not be completed online.
