The Odin Works Billet 9mm Upper Receiver (brand part no. UPPERBILLET9MM) is a stripped upper receiver machined from 7075 billet aluminum specifically for 9mm AR-platform builds, finished in black. It uses a slick-side design with no forward assist, since a 9mm blowback bolt does not need one, and it includes a low-profile brass deflector to keep spent casings clear of the shooter’s face. As a billet receiver rather than forged, it is machined from a solid block of aluminum, which allows for cleaner lines and tighter tolerances than a forged upper. This is a stripped receiver only, so a 9mm-specific barrel, bolt carrier group, and handguard are needed to complete the upper.
