This stripped upper receiver is made from 6061 T6 aluminum and conforms to all mil-spec measurements. Being the A3 type, it also features a "flat top." This means instead of the old-school carry handle that the A2 style used to have, you get a picatinny/1913 rail on top, so you can mount your rear sight or whatever optics you want. You install the forward assist assembly and the dust cover assembly, and then your upper is ready to be integrated into the rest of your AR build.
- Fully stripped
- Made of 6061 T6 billet aluminum
