This piston-driven upper features a 14.5-inch heavy chrome-lined barrel, delivering an excellent balance of velocity, accuracy, and durability for a wide range of applications. Short-Stroke Piston System The BRN-4 upper utilizes a proven short-stroke piston operating system. By keeping combustion gases away from the bolt carrier group, this design significantly reduces carbon fouling inside the receiver, resulting in improved reliability, easier maintenance, and more consistent performance compared to traditional direct impingement systems. 14.5-Inch Heavy Chrome Lined Barrel This upper is equipped with a 14.5-inch heavy profile barrel that is chrome lined for superior longevity and resistance to wear. The chrome lining protects the bore from the erosive effects of high-volume shooting and harsh cleaning chemicals, making it an excellent choice for duty, training, or high-round-count applications. Heavy Barrel Profile The heavy barrel profile provides increased rigidity and heat dissipation, helping maintain accuracy during sustained fire. Combined with the 14.5-inch length, this barrel offers improved muzzle velocity compared to shorter barrels while remaining relatively compact.
