Claim:
Apparatus comprising a firearm sight having a housing with a pair of lens openings on opposite sides of the housing, and a pair of lens covers, one for each lens opening, the housing having a recess receiving the lens covers, each lens cover being biased toward the recess and being moveable against the bias on the lens cover to a position in which the lens cover covers a respective lens opening, wherein the recess and the lens covers are configured such that (i) the lens covers are received and oriented in the recess in a predetermined relation with each other and (ii) the lens covers can be efficiently manipulated when the lens covers are not received in the recess in the predetermined order to cause the lens covers to be reoriented and received in the recess in the predetermined relation; wherein each lens cover is pivotally supported on the housing in a manner that enables the lens cover to be pivoted about a pivot axis toward and into the recess in the housing and to be pivoted about the pivot axis relative to the housing as the lens cover is moved against the bias on the lens cover and to a position in which the lens cover covers a respective lens, and wherein the lens covers are offset in relation to their pivot axes in a manner that enables them to be received and oriented in the recess in the predetermined relation, and oriented in a manner that enables the lens covers to be efficiently manipulated and reoriented when they are not received in the recess in the predetermined relation; wherein each lens cover has a finger tab positioned outboard of the lens cover and formed in one piece with the lens cover, each finger tab configured to enable the lens cover having the finger tab to be manipulated to pivot the lens cover against the bias on the lens cover and into a position in which the lens cover covers a respective lens opening; wherein the housing has a pair of integral detents, each of which is configured to engage a finger tab of a lens cover and hold the lens cover in position in which the lens cover covers a respective one of the lens openings, and wherein the finger tabs on each of the lens covers, and the pair of detents configured such that the finger tab on a lens cover can be manipulated to release the lens cover from one of the pair of detents and allow the lens cover to pivot under the bias on the lens cover toward the recess; and wherein the housing has recesses for receiving the finger tabs, and wherein the detents extend through detent openings in the housing and partially into the recesses that receive the finger tabs.
