Finally get a quality, true-to-form reproduction M16A1 Upper Receiver for a fraction of the cost. Building off of the popular stripped version of this Upper Receiver, we are happy to announce the M16A1 Assembled Upper Receiver. These are machined from 7075-T6 forgings specifically designed to have the correct proportions and profile of the original M16A1 Upper Receiver. They are then installed with a Mil-Spec Dust Cover, a Teardrop Forward Assist, and a Rear Sight. Machine work is performed by true craftsmen with careful attention to detail.
