Description
The Standard Manufacturing Co. STD15 upper receiver is completely manufactured in–house alongside the STD15 Lower receivers. As with the STD15 lower receivers, the STD15 uppers are constructed to the most exacting tolerances and to the highest quality control levels. The STD15 upper receiver begins with a 7075T6 aluminum forging and is machined on the very best aerospace machinery in the business. At every step of the manufacturing process each upper receiver is quality checked before continuing to the next operation. The STD15 upper receiver is the only option we can recommend when using the STD15 lower and because the STD15 uppers are MILSPEC they can be used with other manufacturers’ lower receivers.
