CMT Tactical UPUR-1 Billet AR15 Upper Receiver AR-15


The Cross Machine Tool Ultra Precision Upper Receiver Part# UPUR-1 is the perfect premium quality upper for any Mil-Spec lower build.  The UPUR-1 is machined from Billet 7075 T6 Aluminum unlike the more commonly used 6061. Using the 7075 T6 aluminum gives the UP-UR a 65% increase in strength & 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 & feel to the AR15 platform weapon system.
