About this product

Premium 80% Lower Fire/Safe Marked – Billet The premium 80% lower fire/safe marked – billet delivers the material integrity and dimensional accuracy required for a reliable build. Machined from 7075-T6 aluminum billet, this lower receiver blank is ready for finishing with a jig and router. The fire/safe markings are laser-etched to MIL-SPEC depth and alignment, providing clear, permanent selector reference points. This is a purpose-built component for the builder who demands billet-grade tolerances without compromise. Overview This premium 80% lower fire/safe marked – billet is manufactured from a solid block of 7075-T6 aluminum, then hard-coat anodized to Type III Class 2 for wear and corrosion resistance. The pocket is fully machined to 80% completion, leaving the trigger cavity, fire control group shelf, and selector detent channel un-machined for ATF-compliant home finishing. The fire/safe markings are laser-engraved on the receiver body, ensuring they remain visible through the finishing process and subsequent coating. This is a serial-number-free component; no FFL is required for transfer, though a background check may apply per state law.
