• said mounting block being further formed to define a through bore extending from said floor of said recess through said bottom surface of said mounting block;
• a yoke member configured to be removably received in said recess;
• fastening means on said yoke member for releasably fastening said yoke member to the swivel mounting stud of the forearm stock of the firearm;
• a threaded stud projecting downwardly from said yoke member, said threaded stud being sized and positioned to extend through said through bore and to protrude from said bottom surface of said mounting block when said yoke member is disposed within said recess;
