A translatable archery bow sight assembly that allows the sight to be vertically adjusted with a rotating shaft located within a vertically oriented carriage thereby protecting the shaft, rotation of the shaft causing a sight bracket to raise and lower whereby the sight bracket is adapted for receiving a sight pin, the shaft being rotated by a knob, and the knob including a polymeric bushing in contact with the carriage, the archery bow sight assembly including a stop means for retarding the movement of the pin, the stop means, for example, being surface features included in the knob such as notches which mate with a ball and a spring located within a bore in the carriage. The sight bracket is closely fitted around the carriage and includes bracket sleeves and rubber gaskets to insure a tight fit between the sight bracket and carriage. The sight bracket also includes a pin and a tongue, the tongue being threadedly engaged with the rotating shaft such that the shaft rotation causes the sight bracket to raise and lower as to alter the distance for which an archer is aiming. The pin and the tongue are in displaceable cooperation such that depression of the pin causes the tongue to disengage from the rotating shaft as to permit quick movement of the sight bracket along the length of the carriage.
