About this product

80% Lower Fire/Safe Marked – Anodized Black

Overview

Precision-engineered for builders who demand clarity and reliability, this 80% lower fire/safe marked – anodized black component delivers the foundational markings you need for a clean, professional AR-platform build. Each receiver is machined to industry-standard dimensions, ensuring compatibility with mil-spec upper receivers and parts kits. The fire/safe markings are laser-etched for permanent visibility, eliminating guesswork during range sessions or duty use. Whether you are completing a custom pistol or a dedicated rifle, this 80% lower provides the correct selector markings without requiring a serial number or FFL transfer at purchase.

Features & Specs

This 80% lower fire/safe marked – anodized black unit is manufactured from 7075-T6 aluminum for a balance of strength and weight. The hardcoat anodized finish resists corrosion, abrasion, and solvents, maintaining its matte black appearance through heavy handling. Each lower is inspected for lug engagement, trigger pocket depth, and pin hole alignment before shipment.

  • Material: 7075-T6 aluminum billet; Type III Class 2 hardcoat anodized black finish
  • Markings: Laser-etched fire (semi-auto pictogram) and safe (white-filled) on both sides; caliber and manufacturer markings included
  • Compatibility: Accepts all mil-spec AR-15 LPKs, buffer tubes, and upper receivers; no additional modifications required for standard selector function

All critical surfaces are pre-machined to 80% completion, leaving only the trigger pocket, fire control group pin holes, and selector detent channel for the end user to finish. The fire/safe markings are positioned to align perfectly with standard 90-degree throw selectors, providing unambiguous visual confirmation of your selector position.

Who It’s For

This 80% lower fire/safe marked – anodized black is designed for the intermediate to advanced home builder who values correct factory-style markings without the wait or cost of a serialized receiver. It suits hobbyists constructing a spare lower, competitors needing a dedicated match lower, or anyone who prefers to complete their own firearm using manual milling tools or a jig system. The anodized black finish matches standard mil-spec upper receivers, making it ideal for both new builds and retrofits. Because it is not a firearm, there are no background check delays or transfer fees when purchasing this component.

  • Home builders completing their first or tenth AR lower
  • Competition shooters requiring consistent fire/safe visual indicators
  • Gunsmiths stocking inventory for custom builds or client projects
