Sons of Liberty Gun Works Liberty Fighting 5.56mm 16"1/2x28 Muzzle Thread Midlength 5R Med Contour Chrome Lined/Phosphate Barrel 16-LFB-556CL

The Sons of Liberty Gun Works Liberty Fighting 16" Chrome Lined Barrel is a full-featured, combat-ready barrel engineered for AR-15 platform rifles seeking maximum velocity, enhanced ballistic performance, and reliable function in a non-NFA compliant configuration. Chambered in 5.56mm NATO and featuring a 5R medium contour rifling profile with a midlength gas system, this barrel delivers superior accuracy, reduced fouling, smoother cycling, and consistent performance under sustained fire and demanding field conditions compared to carbine-length gas system alternatives. The chrome-lined bore and chamber provide outstanding corrosion and wear resistance for extended service life, while the phosphate exterior finish offers reliable protection against the elements and hard use. Threaded at 1/2x28 for compatibility with a wide range of muzzle devices and suppressors, the 16" configuration maximizes muzzle velocity and downrange energy from the 5.56mm NATO cartridge while remaining fully compliant for civilian use, delivering the combat-proven reliability, precision craftsmanship, and uncompromising quality that Sons of Liberty Gun Works is renowned for.
