a housing extending in a longitudinal direction;
a bore selector element rotatably mounted to the housing and rotatable about an axis extending substantially transverse to the longitudinal direction, the bore selector element comprising:
a first passage extending through the bore selector element and configured to connect the monobore riser to the production bore at a first rotational position of the bore selector element, and
a second passage extending through the bore selector element and configured to connect the monobore riser to the annulus bore at a second rotational position of the bore selector element;
a first connector for connection to the monobore riser; and
a monobore adapter disposed between the bore selector element and the first connector,
wherein the monobore adapter defines a portion of a seat within which the bore selector element is rotatable, and
wherein rotation of the bore selector element is configured to shear a wireline medium between the bore selector element and the monobore adapter and/or a bore isolator.
