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.

Features

  • Cold Hammer-Forged Construction – Crafted from 4150 Chrome Moly Vanadium (CMV) steel, ensuring exceptional strength, longevity, and heat resistance under high rates of fire.
  • Melonite QPQ Finish – Provides superior corrosion and wear resistance, reducing barrel fouling and extending overall service life.
  • Intermediate-Length Gas System – Offers smoother cycling, reduced recoil, and enhanced reliability, balancing mid-length and rifle-length gas system performance for optimal function.
  • 1:7 Twist Rate – Stabilizes a wide range of bullet weights, from lightweight varmint rounds to heavy, long-range projectiles, maximizing accuracy at various distances.
  • .750 Gas Block Journal – Compatible with standard AR-15 gas blocks, allowing easy installation and customization.
  • Threaded 1/2×28 Muzzle – Ready for muzzle devices or suppressors, providing customization options for recoil management and noise reduction.
