A rear sight for a firearm, the rear sight comprising:
- (a) a rear sight blade connected to a mounting base, which is configured to be mounted on a top surface of the firearm, wherein the rear sight blade includes a first sighting notch, the mounting base being provided with a plunger having a ball and a biasing member;
- and
- (b) a second sighting notch provided on a sliding element, the sliding element being provided with a plurality of detents, the second sighting notch being integrated within the rear sight and configured to translate via linear motion and in a lateral direction perpendicular to a lengthwise direction of the top surface of the firearm so as to move between a first notch position and a second notch position, such that the first sighting notch is an effective sighting notch of the rear sight when the second sighting notch is in the first notch position and such that the second sighting notch is the effective sighting notch of the rear sight when the second sighting notch is in the second notch position,
- wherein the plurality of detents are configured to maintain the sliding element such that the second sighting notch is in the first notch position or the second notch position when the ball of the plunger configured to act on the sliding element is positioned in at least one of the detents.
A method of varying a width of a sighting notch, which comprises a rear sight of a firearm, the method comprising:
- connecting a rear sight blade to a mounting base adapted to be mounted on a top surface of the firearm, the rear sight blade including a first sighting notch;
- and
- positioning a second sighting notch such that the second sighting notch is provided on a sliding element, the second sighting notch being integrated within the rear sight,
- the sliding element being provided with a bar disposed on a side surface of the sliding element proximate to the rear sight blade and configured to slidably engage with a groove on a rear side of the rear sight blade, the bar extending in a lateral direction perpendicular to a lengthwise direction of the top surface of the firearm, and the bar projecting from the side surface of the sliding element in a direction toward the rear sight blade;
- and
- translating via linear motion, in the lateral direction perpendicular to the lengthwise direction of the top surface of the firearm, the second sighting notch between a first notch position and a second notch position, such that the first sighting notch is an effective sighting notch of the rear sight when the second sighting notch is in the first notch position and such that the second sighting notch is the effective sighting notch of the rear sight when the second sighting notch is in the second notch position, the groove allowing the sliding element to slide such that the second sighting notch is movable between the first notch position and the second notch position.
