If you're building or upgrading an AR platform rifle, a quality 5.56 NATO barrel is foundation. The Lead & Steel LS556MED-PIST-7.5 is a 5.56 NATO barrel designed for pistol-length builds, featuring a government profile and finished in black nitride for durability and corrosion resistance. Built from chrome moly vanadium steel, it's engineered to handle the demands of range work, tactical training, and hunting applications where a compact, carbine-length platform makes sense.
The black nitride coating protects the barrel from rust and wear while maintaining a professional appearance. Chrome moly vanadium steel is a time-tested choice in the firearms industry—it offers a balance of strength and machinability that manufacturers rely on for consistent performance. With a 7.5-inch length, this barrel suits pistol-configured AR builds or compact defensive setups where velocity and maneuverability are traded deliberately.
Whether you're swapping in a fresh barrel or assembling your first AR from parts, this Lead & Steel offering gives you a straightforward, no-frills component built to spec. Government profile means it'll work with standard AR handguards and accessories, so integration into your existing platform or new build is hassle-free.

Yes. The government profile is the standard profile used on most AR-pattern rifles and handguards, so compatibility with typical aftermarket and factory handguards is straightforward.
Government profile is the standard, original profile used on military and civilian AR-15s. It's slightly thinner than some aftermarket profiles, which keeps weight down while maintaining strength for 5.56 NATO pressures.
Yes. The black nitride finish is complete and ready to use once properly installed and headspaced on your upper receiver.
Chrome moly vanadium is a durable alloy that resists heat and stress, making it a reliable choice for high-pressure rifle barrels. It balances performance with cost-effectiveness across a wide range of shooting applications.
