A fiber optic connector with a hub extension positioned on the hub of the connector. Prior to assembly of the connector with the rear boot, the hub and ferrule assembly can be pushed backward within the front and rear housings to clear an anti-rotation portion of the front housing and turned for tuning. After complete assembly of the rear boot, the hub extension bottoms out against the boot prior to the hub and ferrule assembly disengaging the anti-rotation portion of the front housing, thereby maintaining the tuned position.
