If you're running a 9mm AR pistol or AR9 platform and need a drop-in replacement barrel, the Lead & Steel LLC LS9mm5.5-28 AR9 9mm Straight Profile barrel delivers the durability and reliability you expect from a serious shooter. This 9mm AR barrel features a straight profile design suited to AR9 builds, constructed from chrome moly vanadium steel and finished with black nitride for corrosion resistance and a long service life. Whether you're building a new upper, swapping barrels for maintenance, or keeping a spare on hand, this is a direct fit for standard AR9 platforms.
The black nitride coating protects against rust and wear while maintaining the clean, professional look of a working gun. Chrome moly vanadium steel is a proven choice for AR barrels—tough enough for high-round-count shooting sessions and reliable in both range work and field conditions. The straight profile keeps weight and cost reasonable compared to heavier contours, making this barrel a practical option for shooters who don't need a rifle-length setup.
Lead & Steel LLC barrels are built with the AR platform ecosystem in mind, so installation is straightforward on any compatible AR9 upper receiver. This is a component designed for shooters who understand their platform and want quality parts without the premium price tag of boutique brands.
