Premium Fire/Safe Marked Billet 80% Lower Assembly

About this product

Premium Fire/Safe Marked Billet 80% Lower Assembly Designed for the discerning builder who demands precision from the ground up, this premium fire/safe marked billet 80% lower assembly represents a critical foundation for your custom AR-platform project. Machined from a solid block of 7075-T6 aluminum, this component offers the dimensional integrity and material strength expected by serious hobbyists and professional armorers alike. The fire/safe markings are laser-engraved to military-spec depth and clarity, ensuring long-term legibility through multiple finish applications. As an 80% lower, this assembly requires final machining of the fire control pocket and trigger pin holes, placing you in control of the build process while adhering to current ATF guidelines regarding unfinished receivers. Overview This premium fire/safe marked billet 80% lower assembly is constructed using billet machining techniques that provide tighter tolerances and sharper geometry compared to forged alternatives. The 7075-T6 aluminum alloy offers superior tensile strength and corrosion resistance, making this lower suitable for both range use and demanding field conditions. The billet construction allows for enhanced material density around critical stress points, including the buffer tube threads and trigger pin lugs. Each unit undergoes dimensional inspection to verify compliance with mil-spec blueprint standards before leaving the manufacturing facility. Features & Specs Material: 7
