The 8" .300BLK complete upper receiver offers the end user an assembled system that is ready for lightweight needs. Each assembled upper starts with a BALIOS-lite stripper upper receiver. We then add our titanium gas block on the appropriate length barrel, and finish the assembly with our 7" BL-RAIL and titanium barrel nut. These uppers are perfect for those who are looking to do a suppressed .300BLK build. Our full mass carrier is included as well as a BCM-Mod4 charging handle.
