The USC 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 that offer ultra smooth operation. The USC upper is machined from Billet 7075-T6 certified
