A sight adjustment process specific to the AR-15 platform ensures accurate bullet impact at a close range. This involves aligning the rifle’s sights (iron sights or optics) so the point of aim and point of impact converge at approximately 25 yards. This establishes a foundational ballistic trajectory allowing for accurate shots at both closer and farther distances, given the projectile’s parabolic flight path.
This short-range sighting-in process offers several advantages. It allows for quick and efficient adjustments, requiring less ammunition and range time compared to longer-range zeroing. The 25-yard zero is particularly well-suited for home defense and close-quarters scenarios, reflecting the most likely engagement distances for civilian AR-15 owners. Historically, military and law enforcement have utilized similar close-range zeroing methods for carbines and similar weapons platforms to optimize effectiveness in urban or confined environments.
