The Cross Machine Tool Ultra Precision Upper Receiver is the perfect match with any mil-spec lower. The UPUR-1 is machined from billet 7075 T6 aluminum unlike the more commonly used 6061. Using the 7075 T6 aluminum gives the UPUR a 65% increase in strength and rigidity over 6061 aluminum receivers. The UPUR-1 is machined on a 5 axis machining center to reduce the number of operations / setups required to complete. This machining process allows the highest possible accuracy to be obtained over the traditional 3 or 4 axis machining method. The UPUR-1 is designed for increased function, performance & to provide an advanced modern appearance and feel to the AR15 platform weapon system. For complete and current information on this item please see the manufacturer's website.
