Lead & Steel Llc LS-SURF-FDE 223/5.56 7075-T6 Aluminum

The Lead & Steel LLC LS-SURF-FDE .223/5.56 upper receiver delivers precision engineering for shooters demanding reliability in modern rifle platforms. Built from mil-spec 7075-T6 aluminum, this component serves law enforcement, military, and civilian operators who require repeatable accuracy and durability in high-round-count applications. The Flat Dark Earth finish provides the tactical aesthetics and corrosion resistance necessary for field operations, whether you're training, competing, or deploying in demanding environments.

7075-T6 aluminum is an aerospace-grade alloy chosen by professional armories for its superior strength-to-weight ratio and dimensional stability under sustained fire cycles. This material resists warping and maintains tolerances critical to bolt carrier group function and optics mounting repeatability. The LS-SURF-FDE upper receiver accommodates standard .223 Remington and 5.56 NATO ammunition, with a design optimized for carbine-length configurations typical of modern tactical rifles. Weighing just 0.67 pounds, the receiver reduces overall rifle mass without compromising structural integrity—a measurable advantage during extended operations or movement-heavy scenarios.

Professional gunsmiths and platform builders integrate this upper receiver into AR-pattern rifles for mid-range to precision work, where upper receiver rigidity directly impacts group consistency. The Flat Dark Earth finish blends with modern tactical gear and environmental backdrops, making it equally suited for duty, training, or competition builds. Installation requires standard AR-platform tools and familiarity with receiver assembly; compatibility extends to all standard .223/5.56 bolt carrier groups, charging handles, and furniture designed for conventional upper receiver geometry.
