Lead & Steel 11.3" AR9 Nitride Barrel 1/2x28

Lead & Steel AR9 Nitride Barrel

This 11.3-inch AR9 barrel represents a straightforward approach to 9mm carbine building. Chambered in 9mm Luger, it features a straight profile that simplifies installation and maintenance.

Key Features

• Material: Chrome moly vanadium steel with black nitride finish for durability and corrosion resistance
• Length: 11.3 inches, ideal for compact AR9 builds
• Threading: 1/2x28 muzzle threads for standard 9mm suppressors and muzzle devices
• System: Blowback operation—no gas block or gas tube required
• Compatibility: Works with standard mil-spec uppers and dedicated AR9 uppers

Design Philosophy

The blowback design eliminates complexity. Without a gas system to tune or maintain, you get a simpler, more reliable platform. This barrel pairs easily with standard AR components, making it an excellent choice for builders seeking straightforward 9mm performance.

The black nitride finish provides reliable protection against wear and corrosion, while the chrome moly vanadium construction ensures consistent performance across extended shooting sessions.
