Rosco Manufacturing K9 AR-15 Barrel - 13.95" - 5.56 NATO - Mid-Length - w/ Gas Tube

13.95″ Barrel For a Balance of Great Ballistics and Improved Ergonomics

The Rosco Manufacturing 13.95 K9 5.56 NATO AR-15 Barrel with Midlength Tube is the ultimate duty-ready upgrade for shooters seeking a balance of accuracy, durability, and smooth recoil. The midlength 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.
• MIdlength Gas System – Offers smoother cycling, reduced recoil, and enhanced reliability. Midlength gas systems are an improvement over carbine length for recoil impulse and suppressed use.
• Optimized Gas Port – An optimized gas port ensures proper gas control while using the barrel suppressed while also allowing enough gas through to reliably cycle while shooting unsuppressed.
• 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.
