Our uppers are assembled by SOTAR-trained master armorers in North Carolina using components manufactured exclusively in the USA.
Below are some highlights of features of our Pugio-9EM upper:
- Aero Precision EPC Enhanced Upper Receiver
- The Aero EPC upper has the best combination of features, quality, and value for a dedicated PCC. It offers unlimited potential for a build.
- Barrel: Ballistic Advantage 8.3″ Straight Profile, 4150 CroMoV, QPQ Barrel, 9mm Luger
- Bolt: Cryptic Coatings Phosphate PCC Bolt
- Cryptic Coatings makes the best and most affordable PCC bolts. The phosphate bolt is the equivalent to the Mil-Spec BCG in the AR-15.
- Charging Handle: Mil-Spec Charging Handle
- Muzzle Device: Mil-Spec A2 Flash Hider
Critical finishes and dimensions of individual components are inspected before we accept them into inventory. To learn more about our quality control gauging and inspection, visit our Quality Promise page.
Each upper receiver includes the following assembly and QC steps (full schedule of all 82 points of inspection for our builds can be found in our Quality Promise page):
