Forged Fire/Safe Marked 80% Lower Assembly

The forged fire/safe marked 80% lower assembly is a precision-machined component designed for builders who require a Mil-Spec platform with clear, permanent selector markings. This lower assembly starts as a raw forging and is machined to 80% completion, leaving the final material removal steps to the end user. It provides a reliable foundation for a custom AR-15 build, with engraved fire and safe indicators that ensure compliance and clarity.

Overview

This lower assembly is manufactured from a high-strength aluminum forging, heat-treated and hard-coat anodized for durability. The fire/safe markings are laser-etched and filled for long-lasting visibility. As a forged fire/safe marked 80% lower assembly, it is compatible with standard AR-15 upper receivers and parts kits. The 80% completion status means it is not a firearm and can be shipped directly to your door without an FFL transfer, pending your completion of the final machining steps.

Features & Specs

• Material: Forged 7075-T6 aluminum for high strength and impact resistance; hard-coat anodized finish per Mil-Spec Type III Class 2.
• Markings: Permanent “FIRE” and “SAFE” selector engravings, color-filled for high contrast; includes “FORGED” manufacturer mark as part of the forging process.
• Compatibility: Accepts standard AR-15 lower parts kits, buffer tubes, and pistol grip assemblies; designed for use with .223/5.56 and .300 Blackout calibers.

Additional specifications include a machined trigger pocket, bolt catch recess, and selector detent channel to Mil-Spec tolerances. The forged fire/safe marked 80% lower assembly is ready for your jig and router to complete the fire control pocket and trigger pin holes.

Who It’s For

This lower assembly is intended for experienced firearm builders who possess the necessary tools and knowledge to complete an 80% lower. It is ideal for hobbyists, gunsmiths, and enthusiasts who want a marked lower with clear fire/safe indicators without the restrictions of a completed firearm. If you are building a custom AR-15 from a forged fire/safe marked 80% lower assembly, ensure you are compliant with all local, state, and federal laws regarding unfinished receivers. This product is not for those seeking a drop-in, ready-to-fire component.

Shipping & FFL

Because this item is an 80% lower assembly and is not classified as a firearm under federal law, it can be shipped directly to your residence without requiring an FFL transfer. No background check is needed for purchase. However, it is your responsibility to verify that possession and completion of this forged fire/safe marked 80% lower assembly are legal in your jurisdiction. Some states and localities impose restrictions on unfinished receivers. By purchasing this product, you confirm that you are legally allowed to own and complete it. Once machined into a functional lower receiver, it must be serialized and transferred in compliance with applicable laws. Forged Fire/Safe Marked 80% Lower Assembly shipments are sent via ground service with signature confirmation.

This lower assembly is a parts component only. The end user assumes all liability for legal compliance during and after the completion process. Always consult a firearms attorney if you have any questions regarding your specific situation.
