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 American Made 7075-T6 forgings specifically designed to have the correct promotions 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.
Please note these upper receivers have M4 feed ramps for improved compatibility and reliability when using modern barrels.
This is the proper upper to use for the following reproduction builds:
- Model 607
- Model 609 (XM177E1)
- Model 619
- Model 629 (XM177E2)
- Model 639
- Model 651
- Model 653
