Forged Fire/Safe Marked 80% Lower Assembly

The foundation of any precision-built AR-15 platform begins with a reliable, un serialized receiver. The Forged Fire/Safe Marked 80% Lower Assembly represents a critical starting point for the serious builder seeking a durable, mil-spec compatible platform. Machined from a solid 7075-T6 aluminum forging, this lower receiver is precisely indexed for completion with standard jigs and tooling. The fire/safe markings are laser-etched for permanent legibility, ensuring compliance with visual safety protocols without adding unnecessary bulk or coatings. For the hobbyist or professional gunsmith, this component offers the structural integrity required for high-round-count builds while maintaining the flexibility of an unfinished part.

Overview

This forged fire/safe marked 80% lower assembly is designed for the end user who demands exacting tolerances and material honesty. Unlike billet receivers that require extensive machining to achieve proper geometry, this forging captures the grain flow of the aluminum for superior strength under stress. The 80% completion stage means the fire control pocket, trigger slot, and safety selector holes are partially pre-machined, reducing the risk of critical alignment errors during final milling. The hardcoat anodized finish resists corrosion and wear, preserving the integrity of the safety markings through repeated handling. Each unit is inspected for dimensional consistency against mil-spec TDP standards, ensuring compatibility with standard lower parts kits and upper receivers.

Features & Specs

The specification sheet for this component reads like a checklist for serious builds. The forging process eliminates weak points common in cast or poorly machined parts, while the 80% state allows the builder to complete the receiver according to their own standards. Key specifications include:

• Material: 7075-T6 aluminum forging with Type III Class 2 hardcoat anodized finish; weight approximately 9.6 ounces raw
• Markings: Permanently laser-etched “FIRE” and “SAFE” indicators on both sides, with “FORGED” rollmark on magazine well; no serial number present
• Pocket Dimensions: Trigger pocket machined to 1.240 inch depth; safety selector hole pre-drilled to 0.245 inch diameter; rear takedown pin lug and buffer tower threads intact

Additional structural details include a reinforced front pivot pin lug area, a flared magazine well for faster reloads, and an integral trigger guard that accepts standard roll pins. The lower is compatible with all mil-spec AR-15 upper receivers and uses standard buffer tube threads (1.250 inch-18). The fire/safe markings are positioned exactly 0.375 inches from the safety selector hole center, meeting industry standard visual reference distances.

• Tolerance: Critical pin hole diameters held to +/- 0.0015 inches; overall length within 0.010 inches of mil-spec dimensions
• Compatibility: Accepts all standard AR-15 lower parts kits, drop-in triggers, and pistol grip configurations; requires final machining of trigger slot depth and safety detent channel
• Packaging: Individually wrapped in vapor-inhibiting paper; includes receiver extension nut and castle nut (buffer tube not included)

Who It’s For

This forged fire/safe marked 80% lower assembly is specifically engineered for the intermediate to advanced builder who has access to a drill press, end mill, or router jig system. It is not a complete receiver and requires approximately 2 to 4 hours of finishing work to achieve functional status. The intended audience includes hobbyists who wish to create a personally owned firearm without a serialized record, custom gunsmiths building matched sets for competition or hunting, and collectors who prefer the material advantages of a forged receiver over billet alternatives. This product is also suitable for educational workshops where students learn receiver finishing techniques under instructor supervision. Because the lower is not a firearm under federal regulation until completed, it can be shipped directly to your home or business without an FFL transfer for the initial purchase.

Shipping & FFL

This item is classified as a non-firearm component under current ATF rulings and may be shipped directly to your residential or commercial address. No Federal Firearms License (FFL) is required for the purchase or shipment of this 80% lower assembly. However, once you complete the machining and assembly process, the resulting firearm must comply with all applicable federal, state, and local laws regarding possession, transfer, and serialization. It is your responsibility to verify that the final product is legal in your jurisdiction. Forged Fire/Safe Marked 80% Lower Assembly shipments are processed within 1-3 business days via UPS Ground or FedEx Home Delivery. International shipping is not available. By purchasing this product, you acknowledge that you are not prohibited from owning firearms under state or federal law and that you will complete the receiver in compliance with all applicable regulations.
