Blackout Defense’s Ultra Precision Upper Receiver is the perfect Mate to our ModA and ModB lower receivers or would also be a great match with any Mil-Spec lowers. Our uppers are machined from Billet 7075-T6 Aluminum. Using the 7075 -T6 aluminum gives our upper receiver 65% increase in strength & rigidity over 6061 aluminum receivers. Our upper receiver is machined on our 5 Axis DMG MORI machining Center to reduce the number of operations and setups. This machining process allows the highest possible accuracy to be obtained over the traditional 3 or 4th Axis machining method.
