Product Description

The LanTac UAR Billet Upper Receiver is a precision-engineered AR-15 stripped upper receiver machined from certified 7075-T6 aluminum billet. Built around LanTac's patent-pending SMOOTHCAM system, this upper receiver incorporates a specially contoured cam pin recess that works in concert with a domed head, low-friction cam pin to deliver exceptionally smooth bolt carrier group movement. The proprietary bore achieves a roughness average of just 16 micro inches, far superior to the 32-63 micro inch average found on standard bored or milled uppers, dramatically reducing internal friction and wear over time. Barrel nut threads, bore, and barrel extension surfaces are all machined in a single operation to guarantee perfect concentricity and perpendicularity, contributing to a more accurate and consistent platform. Finished with a Type 3 Class 2 Deep Black Hardcoat Anodized coating for outstanding durability and corrosion resistance, the LanTac UAR is the ideal foundation for any high-performance AR-15 build.
