A telescopic sight is provided that includes an integral mounting bar for connection to a barrel of a firearm and integral auxiliary equipment mounting features for mounting auxiliary equipment onto the telescopic sight. The auxiliary equipment mounting features facilitate the mounting of multiple devices that allows for quickly alternating between different aiming devices or to simultaneously use multiple aiming devices. Clamp assemblies cooperate with the mounting bar to secure the telescopic sight to the firearm and provide adjustment of the height position of the telescopic sight. The clamp blocks are adapted to fit onto a mounting rail of a firearm. The mounting features are universal and require no post-mounting adjustment to accurately align the auxiliary equipment.
