The Lead & Steel LS300-16 is a drop-in AR9 300 Blackout barrel built for shooters who want a proven, no-fuss upgrade. Whether you're tuning a carbine for subsonic loads, competition, or hunting, this 16-inch government profile barrel gives you a solid foundation without the guesswork. The chrome moly vanadium steel construction and black nitride finish deliver corrosion resistance and durability in a package that's ready to install and shoot.
Government profile barrels are the standard on military and law enforcement rifles for good reason—they're robust, they cool evenly, and they hold their zero through extended shooting sessions. This barrel maintains that proven geometry while being tailored to the 300 Blackout cartridge, so you get the velocity and accuracy the round is known for without over-engineering the profile for your needs.
Lead & Steel built this barrel with accuracy in mind. The 300 Blackout thrives at moderate velocities, especially with subsonic ammunition, and a quality barrel is where that performance starts. Black nitride finishing protects against rust and fouling while keeping cleanup straightforward. If you're building or upgrading an AR9 platform, or swapping barrels to experiment with a new caliber, the LS300-16 gives you a no-compromise option that won't slow you down.

Yes, the LS300-16 is designed as a drop-in barrel for standard AR9 platforms. It uses government profile dimensions, which are the industry standard for AR compatibility.
Black nitride resists rust and corrosion, reduces fouling buildup during shooting, and makes cleaning easier. It also maintains a professional appearance and adds durability without adding significant weight.
The 300 Blackout is commonly loaded subsonic, and this 16-inch barrel will cycle subsonic loads effectively. A quality barrel is essential for consistent velocity and accuracy with any load, including subsonic rounds.
We recommend consulting your AR platform's manual or a qualified gunsmith for barrel installation. Proper headspacing and alignment are critical for safe, accurate operation.
