The UAR is a precision-machined upper with a special burnished bore that gives a compacted internal surface with a roughness average in micro-inches of 16, as opposed to standard bored or milled uppers that are 32-63, or higher. This reduces bolt carrier friction and creates a much smoother operation. The patent-pending SMOOTHCAM system features a domed head, low friction cam pin, and special upper receiver for ultra smooth operation. The UAR upper is machined from Billet 7075-T6 certified aluminum. It is mils-pec, type 3, class 2, deep black, hardcoat anodized. Barrel nut threads, bore and barrel extension surfaces are all machined in one operation so they are perfectly concentric and perpendicular to the barrel and fixing assembly. The cam pin recess has been carefully designed with a smooth surface that flows into the main reciprocation channel.This allows LANTAC's specially designed radial, domed head cam pin to move with the minimum of wear against these internal surfaces. Package Includes CP-R360 Domed head ultra smooth Cam Pin.
