A specialized sheet of paper or other material marked with aiming points and grid lines facilitates zeroing the optics and improving accuracy on an AR-15 platform rifle. These resources often feature contrasting colors and shapes for easy visibility at varying distances and under different lighting conditions. An example might include a bullseye surrounded by numbered or lettered grids for precise adjustments.
Accurate shooting is paramount for safe and effective firearm use. These aiming aids allow shooters to refine their rifle’s point of impact to match the point of aim, ensuring projectiles strike the intended target. This is crucial not only for recreational shooting, but also for hunting or competitive activities. Historically, sighting methods evolved from rudimentary iron sights. Modern tools offer a more precise and efficient path to achieving accuracy, minimizing wasted ammunition and maximizing skill development.
