Arca Rail adapter for Rifle Sighting Front Rest

This is an Arca rail adapter for DJ Foot designed  Rifle Sighting Front Rest. This will attach on the rest with two  ¼-20 x 1 ¼"L bolts . The Arca Rail attachment is held to the adapter with a ¼-20 x ¾"L flat head screw, I did install a brass threaded insert in the adapter for strength. The brass threaded insert is designed for plastic or wood. McMaster Carr p/n 90016A101
