Billet 80% Lower (Raw)
Billet 80% Lower (Raw) – The Premium Aluminum Foundation for Your AR-15/AR-308 Ghost Gun
In 2025, when forged 80% lowers dominate the budget market, the Billet 80% Lower (Raw) stands apart as the choice of serious builders who demand tighter tolerances, smoother finishes, and a receiver that looks as good raw as it does Cerakoted. CNC-machined from a solid block of 6061-T6 aircraft-grade aluminum (not forged or cast), every surface is precision-cut for perfect fitment with mil-spec or premium upper receivers – no sloppy tolerances or casting imperfections.
Available in AR-15 (.223/5.56 & 300 BLK) and AR-308 (.308/6.5 Creedmoor) variants, the raw finish lets you anodize, Cerakote, or leave it natural for that clean billet aesthetic.
Why Choose a Billet 80% Lower in 2025? | Billet 80% Lower (Raw)
- Tighter tolerances – machined from solid billet = zero forging seams or casting porosity
- Smoother surfaces – ideal for custom Cerakote or anodizing jobs
- Integrated trigger guard – no more roll pins or broken guards
- Broached magwell – perfectly square, no hand filing needed
- Threaded bolt-catch hole – screw-in bolt catch instead of roll pin (stronger & easier)
- 100% legal – ships as “non-firearm” to 21+ adults in 42+ states
- No FFL, no serialization, no background check – pure privacy
Real-world feedback from 2025: builders consistently report easier jig alignment, cleaner milling, and zero fitment issues with high-end uppers (Aero, BCM, Noveske, etc.).
