The distance at which a projectile fired from a short-barreled 5.56x45mm rifle can reliably achieve its intended purpose, whether that be accurate target engagement or terminal ballistic performance, is a crucial factor in weapon selection and tactical considerations. For an 11.5-inch barrel, this distance is demonstrably shorter than that of longer-barreled variants due to reduced muzzle velocity. This impacts bullet trajectory and energy retention downrange.
Understanding the limitations imposed by shorter barrels is essential for operators and enthusiasts alike. This knowledge informs decisions regarding engagement distances, ammunition selection, and the overall effectiveness of the weapon system in specific scenarios. Historical data from military and law enforcement applications further underscores the significance of barrel length on projectile performance. This awareness ultimately contributes to safer and more effective firearm usage.
