16" 5.56 NATO 1:9 Twist Phosphate + Chrome-Lined Midlength Heavy Barrel

Tough Enough for Hard Use. Accurate Enough for Precision Work.

The 16" 5.56 NATO 1:9 Twist Phosphate + Chrome-Lined Midlength Heavy Barrel from Black Rifle Depot is built for shooters who need lasting durability and consistent performance under pressure. Its chrome-lined bore resists corrosion and erosion from high-volume shooting, while the phosphate exterior finish adds an extra layer of surface protection. The heavy barrel profile improves rigidity and heat resistance, allowing for tighter groupings during extended strings of fire. With a mid-length gas system, it offers smoother recoil and improved reliability over traditional carbine setups. The 1:9 twist rate delivers versatile accuracy across a wide range of 5.56 bullet weights, making this barrel an ideal choice for training, defense, or general-purpose builds. Backed by our MOA guarantee and manufactured to ISO-9001 standards right here in the USA, this is a high-value upgrade you can count on.
