A 16″ .223 barrel is a standard length AR-15 barrel designed for .223 Remington or 5.56 NATO ammunition, offering a balance of accuracy, velocity, and maneuverability. It works with AR-15 upper receivers, compatible gas systems (carbine or mid-length), gas blocks, gas tubes, handguards, bolt carrier groups, and lower receivers. This barrel length is ideal for versatile AR-15 builds used in target shooting, hunting, and home defense, providing reliable cycling and performance.
