An adjustable reticle is a feature found in some optical sights, such as riflescopes and red dot sights, that allows the user to change the position or style of the crosshairs or aiming point. This adjustment helps shooters align their aim more accurately based on various factors, such as distance to the target or specific shooting conditions. These reticles can be adjusted for windage and elevation, enabling precise targeting. Some models also offer illuminated reticles, enhancing visibility in low-light situations. Overall, adjustable reticles improve shooting accuracy and adaptability for different scenarios.
