Isn't it called a stacking swivel? If that is the case... pulled this off of dictionary.com

–noun
a metal swivel attached to the stock of a military rifle for use in hooking three rifles together to form a stack.

It's a stacking swivel. This silly actor will show you how they were used.

They unstack easily.Hole digging ,etc is sometimes best done with two hands.Stacked weapons are not laying in mud,sand,etc or leaning semi-secure against a tree.
