Premium Fire/Safe Marked Billet 80% Lower Assembly

The Premium Fire/Safe Marked Billet 80% Lower Assembly provides a solid foundation for builders who demand precise markings and reliable material integrity. Machined from 7075-T6 aluminum billet, this lower receiver blank is designed for the serious hobbyist or gunsmith. The crisp fire/safe engraving ensures clear selector indication once the build is complete.

Overview

This product is an unfinished 80% lower receiver, meaning it requires additional machining to become a functional firearm receiver. The Premium Fire/Safe Marked Billet 80% Lower Assembly is pre-marked with standard fire and safe selector positions, eliminating guesswork during final assembly. The billet construction offers improved grain structure compared to forged receivers, resulting in a tighter, more consistent blank. Each unit is machined to mil-spec dimensions within the unfinished areas, ensuring compatibility with standard AR-15 parts kits.
