Can you identify this tool? I believe it is used on firearms.
This tool came in a box of firearm items, however we have been unable to identify what it is or what it would be used for. The overall length is 2 7/8 inches, largest diameter is 3/4 inch, smaller diameter is 7/16 inch, has a 3/16 slot on one end and two 1/8 inch pins in the larger end, pins are 1/2 inch apart. There are two holes cross drilled in the smaller diameter, they are each 3/16 diameter and are 15/16 inch apart. The metal is blued same as a firearm would be. There are no identification markings on this tool.
