Forged Fire/Safe Marked 80% Lower Assembly

For builders seeking a reliable foundation for their next platform, the forged fire/safe marked 80% lower assembly delivers the structural integrity and marked precision required for a professional-grade build. Machined from a single aluminum forging and pre-marked with fire/safe selector indicators, this lower assembly is designed for users who demand accuracy without the premium price tag of a completed unit. As a true 80% lower, it requires final machining of the trigger pocket and fire control group holes, giving you full control over the fit and finish of your firearm.

Overview

The forged fire/safe marked 80% lower assembly is manufactured to mil-spec dimensions using a high-pressure forging process that aligns the grain structure of the aluminum for maximum strength. This lower is compatible with standard AR-15 upper receivers, buffer tubes, and parts kits. The fire/safe markings are laser-engraved into the lower receiver, providing clear, durable selector indicators that will not wear off over time. Whether you are building a custom rifle for competition, hunting, or personal defense, this lower serves as the structural backbone of your weapon system.

Features & Specs

• Forged from 7075-T6 aluminum for high strength-to-weight ratio; hardcoat anodized black per mil-spec Type III Class 2 for corrosion resistance
• Pre-marked with “fire” and “safe” selector engravings on both sides of the lower receiver; compatible with standard GI-type selector switches
• Accepts all mil-spec AR-15 lower parts kits, buffer tubes, and pistol grip configurations; includes integral trigger guard and flared magazine well for faster reloads

This 80% lower assembly is manufactured by Forged, a trusted name in the firearms parts industry, and is categorized as a firearm part requiring final machining before assembly. All critical dimensions, including the pivot pin lugs, rear takedown pin lug, and buffer tube threads, are machined to exact tolerance at the factory. The fire/safe markings are placed at the correct rotational angle for proper selector function after completion.

Who It’s For

This forged fire/safe marked 80% lower assembly is intended for experienced builders, hobbyists, and gunsmiths who have the necessary tools and expertise to complete the fire control group pocket. It is not a finished firearm and requires drilling of the hammer, trigger, and selector pin holes to the specified depth and diameter. If you are a first-time builder, we recommend reviewing instructional guides or working under the supervision of a qualified gunsmith. This product appeals to those who want to customize their trigger feel, select their own parts kit, or create a lower that is legally considered non-firearm until the final machining steps are performed.

Shipping & FFL

Because this is an 80% lower receiver that is not yet a firearm, it does not require transfer through a Federal Firearms License (FFL) dealer for shipping within the United States. However, once you complete the machining process, the resulting firearm must comply with all applicable federal, state, and local laws. It is your responsibility to verify that possession and completion of this product are legal in your jurisdiction. We ship this item directly to your doorstep with adult signature required. Some states and localities restrict the purchase or possession of unfinished lower receivers; check your local laws before ordering. No FFL transfer is required at the time of purchase, but we reserve the right to refuse shipment to prohibited persons or jurisdictions where this product is restricted.
