AR-15 Barrel with Intermediate Gas Tube For Combat-Ready Performance
The Rosco Manufacturing 16″ K9 5.56 NATO AR-15 Barrel with Intermediate Gas Tube is the ultimate duty-ready upgrade for shooters seeking a balance of accuracy, durability, and smooth recoil. The intermediate gas system reduces felt recoil and minimizes bolt carrier group wear, leading to smoother shooting. The 1:7 twist rate and premium bore finish ensure consistent sub-MOA accuracy when paired with quality ammunition. A refined continuous tapered profile for enhanced weight distribution keeps the weight of the barrel closer to the back of the rifle while preserving heat mitigation and precision.
