A center barrel is connected to the outer barrel and has a proximal lip adjacent the first rim of the outer barrel, a distal lip adjacent the second rim of the outer barrel, and a tubular body portion extending from the proximal lip to the distal lip, and extends beyond both the first rim and the second rim. An annular flange curves out and away from the second rim of the outer barrel. A spiral surface is located on the frustoconical body portion of the outer barrel. A nut surface is located on the tubular body portion of the center barrel adjacent the distal lip.
