The M16A2 also introduced a shell deflector to prevent spent casings from hitting left-handed shooters, a heavier barrel to reduce overheating and improve accuracy, and a round handguard for better grip and control. These changes made the M16A2 a more reliable and user-friendly weapon, suitable for a variety of combat scenarios.
Throughout its service life, the M16A2 has been praised for its accuracy and adaptability. It has seen action in various conflicts, including the Gulf War, and has remained a cornerstone of U.S. military small arms. Its legacy continues, influencing the design of subsequent models like the M16A3 and M16A4, as well as the M4 carbine.
