A protector includes a U-shaped body with an upper wall, spaced depending side walls, a rear wall and a unitary forward spring tab. The side walls are respectively pivotally connected to the extension portions and movable between closed and open positions. When closed, all the protector walls, the extension portions and the top wall portion substantially enclose a rear part of the sight, including the lens thereof, to inhibit debris from entering. The polymeric tab engages the top wall portion and biases the protector closed which is overcome automatically by forcible withdrawal of the firearm.
