SIONICS 11.5″ Upper Receiver Group Premium Edition is Precision Machined from 7075-T6 Aluminum to maximize Strength and reduce Weight. The Premium Series features the Tightest Machining Tolerances and most lustrous Midnight Type III Class II Hard Coat Anodize. Tighter Tolerances allow for a tighter Barrel Fit which improves Accuracy and finish. All of our Premium Receivers are THERMAL FIT to the barrel, this furthers the accuracy of the upper receiver group greatly. These uppers come with the SIONICS logo hard engraved above the charging handle and on the opposite side of the ejection port.
