M16A1 Assembled Upper Receiver 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. These uppers are finished with Mil-Spec type 3 hard anodizing which has the best likelihood of matching most mil-spec forged lower receivers. This is the proper upper to use for the following reproduction builds: XM16E1 M16A1 Model 607 Model 609 (XM177E1) Model 619 Model 629 (XM177E2) Model 639 Model 651 Model 653
