U.S. Arms Upper Receiver
Stripped upper receiver, anodized black.
U.S. Arms (USAC) AR-15 Upper Receivers are the most durable, lightweight uppers on the market. This AR-15 stripped upper receiver was engineered to allow significant weight reduction without sacrificing strength. The meticulous details incorporated during the machining and manufacturing process allow for a completely unique product. The face of the receiver is perfectly squared from the CNC process and aligned with the receiver thread. This means that the barrel extension and receiver face will mate up with complete precision without the possibility of a “High or Low side”. During extended firing on the range this will ensure that your shot group will stay centered on the target. This AR-15 upper truly has it all – great looks, dependability, accuracy, and a lightweight composition.

The high-quality anodized finish or Cerakote finish of this receiver allows for corrosion resistance, easy upkeep, and fade resistance. This will ensure your AR-15 is not only operational, but looks great for years to come. The U.S. Arms lower receiver will fit any AR-15 upper receiver on the market and tighten your shot group in the process.
