A bore selector (1) to be used for coupling a monobore riser to a dual bore subsea installation, comprising: - a lower base part (10), which is provided with first and second through bores (11, 12); - an upper selector part (20), which is provided with a through bore (21) to be connected to a bore of a monobore riser, the selector part being movable in relation to the base part so as to allow the through bore of the selector part to be aligned with and connected to a desired one of the through bores of the base part; - an actuator (30) for moving the selector part in relation to the base part; and - a connector sleeve (50), which is slidably mounted in the through bore of the selector part and configured for selective engagement with the first and second through bores of the base part.
