The assembly is selectively maintained in a housing using a, mounting system. The plug and ball seat assembly includes a ball seat selectively connected to the plug. The mounting system is designed such that disengaging the ball seat from the plug also disengages the plug from the housing, thereby releasing the plug. In another aspect, a method of releasing a plug includes selectively connecting a ball seat to the plug and disposing the plug and ball seat assembly within a tubular. When the plug is ready for release, the ball seat is disconnected from the plug and allowed to move axially relative to the plug.
