Lantac USA LA00221 Upper Advanced Receiver, Milspec Type3 Class2, Deep Black Hardcoat Anodized, Black

The patent-pending SmoothCam system incorporates a domed head and low-friction cam pin for exceptionally smooth operation, reducing wear and enhancing reliability during use. Crafted from high-quality billet 7075-T6 certified aluminum, this upper receiver undergoes milspec Type3 Class2 deep black hardcoat anodizing for superior durability and corrosion resistance. Features a precision-machined proprietary bore with a roughness average of just 16 micro inches, significantly lower than standard uppers, to minimize bolt carrier friction and promote seamless functionality. Barrel nut threads, bore, and barrel extension surfaces are machined in a single operation, ensuring perfect concentricity and perpendicular alignment for optimal accuracy and assembly. The carefully designed cam pin recess blends smoothly into the main reciprocation channel, allowing the specialized radial domed head cam pin to operate with minimal wear against internal surfaces. Ideal for firearms enthusiasts, this receiver is built to milspec standards, making it a reliable upgrade for AR-style platforms.
