Description
The 7/16″ diameter head of the post sling stud has been thinned to 5/16″ width and cross drilled to mount our narrow swivel, SWIVEL-4-N. Tapered screw thread as found on many antiques. We recommend drilling a pilot hole with a DRILL-14 (.182″) drill bit when installing this in the stock.
