A sighting-in process for the AR-15 platform involves adjusting the rifle’s sights or optics to align the point of impact with the point of aim at a predetermined distance. This process typically uses a paper or electronic target with clearly defined aiming points and grid markings, allowing for precise adjustments. For example, a common practice is to adjust the rifle to hit the center of the target at a range of 100 yards.
Accurate sighting-in is crucial for the effective use of the AR-15 in various applications, from recreational target shooting to hunting. Properly aligning the sights ensures bullet impact where intended, increasing accuracy and minimizing wasted ammunition. This practice has evolved alongside firearm technology, becoming more refined with the development of advanced optics and sighting systems. Achieving this alignment builds confidence in the shooter and allows for consistent, predictable performance.
