Z-Parts VFC M4 KAC KS1 GBB 13.9 inch Steel CNC Outer Barrel - Black

The Z-Parts 13.9-inch steel outer barrel is the ultimate upgrade for VFC M4 and AR-15 gas blowback users wanting true military specification and total front-end rigidity. It perfectly replicates the authentic Knight Armament Company KS1 profile seen on modern service rifles like the British Army L403A1 without sacrificing skirmish-ready durability. Because it is crafted from precision CNC-machined high-grade steel, this barrel delivers exact weight distribution and completely resists flexing under heavy torque. That monolithic construction guarantees absolute concentricity for your inner barrel, eliminating the hop-up deviation often caused by front-end sag. It features standard 14mm counter-clockwise muzzle threads for easy integration with your favorite flash hiders, suppressors, or tracer units. Finished in a rugged, anti-corrosion matte black phosphate treatment, this barrel is purpose-built for dedicated mil-sim builders looking for precise historical accuracy and uncompromising structural strength in harsh field conditions.
