An optical sight includes: an outer barrel formed with a slot; an objective lens unit and an ocular lens unit mounted to opposite ends of the outer barrel; a magnification unit including a first inner barrel tiltably disposed in the outer barrel, a second inner barrel sleeved on the first inner barrel, lens assemblies movably disposed in the first inner barrel, an adjusting ring sleeved on the outer barrel, and an adjusting pin mounted to the adjusting ring; and an adjustment unit operable to adjust inclination of the first and second inner barrels. The second inner barrel is formed with a driven hole registered with the slot. The adjusting pin extends through and is movable along the slot, and includes a drive end received in the driven hole. The drive end is spherical, and has a diameter that is not larger than a diameter of the driven hole.
