Definition

Noun: 1. A type of rear gunsight: An open sight is a simple, non-magnifying aiming device on a firearm, typically consisting of a notch (a U- or V-shaped groove) at the rear. The shooter aligns this notch with a front sight post and the target to aim. It is characterized by its open, unobstructed design, as opposed to a peep sight (which has a small hole) or a telescopic sight.
