The RL556v3 80% AR15 Lower – Gray comes complete with essential parts as described: RL556V3 80% AR15 Lower – Gray The RL556V3 80% AR15 Lower – Gray is a precision-machined component designed for builders who demand exacting tolerances and a durable, corrosion-resistant finish. Manufactured by RL556V3, this 80% lower receiver serves as the foundation for a custom AR15 platform, requiring final machining to complete the fire control cavity and trigger pocket. Crafted from 7075-T6 aluminum with a hardcoat anodized gray coating, this unit offers the structural integrity and dimensional consistency essential for a reliable build. As a non-serialized component prior to completion, it provides the legal latitude to construct a firearm for personal use in compliance with all applicable federal and state regulations. Overview The RL556V3 80% AR15 Lower – Gray is a purpose-built blank that bridges the gap between raw billet and a fully functional lower receiver. It is precisely jig-drilled and profiled to accept standard AR15 trigger groups, pistol grips, and buffer tubes once the user completes the necessary milling operations. The gray anodized surface reduces glare and resists wear in high-touch areas, making it a practical choice for both first-time builders and experienced gunsmiths. Each unit is inspected for dimensional accuracy against mil-spec drawings, ensuring compatibility with a wide array of upper receivers, stocks, and accessories. The RL556V3 designation reflects the manufacturer's commitment to repeatable quality and consistent wall thickness throughout the magazine well and trigger housing areas. Features & Specs This 80% lower is engineered for precision and longevity. The 7075-T6 aluminum alloy provides superior tensile strength compared to standard 6061 variants, while the Type III Class 2 hardcoat anodizing in gray offers enhanced surface hardness and corrosion protection. The RL556V3 80% AR15 Lower – Gray is machined from a solid billet, leaving no forging lines or porosity that could compromise structural integrity. The trigger pocket, bolt catch recess, and magazine catch pocket are pre-profiled to minimize material removal during finishing, reducing the risk of over-machining. All critical dimensions are held within +/- 0.002 inches, ensuring a snug fit with mil-spec LPKs and buffer assemblies. Material: 7075-T6 aluminum billet, hardcoat anodized in gray Precision: CNC-machined to mil-spec tolerances, trigger pocket pre-profiled Compatibility: Accepts all standard AR15 small parts, grips, and buffer tubes Who It's For The RL556V3 80% AR15 Lower – Gray is intended for the DIY builder who values control over every aspect of their firearm's assembly. It suits individuals who prefer to complete the fire control cavity using a drill press, router, or hand tools, granting full authority over the final fit and finish. This component is also appropriate for those who wish to maintain a non-serialized lower for personal use, provided they comply with all local and federal laws regarding firearm manufacture. The gray finish appeals to builders assembling a subdued, tactical-themed rifle or those matching existing gray anodized upper receivers and handguards. Because the RL556V3 80% AR15 Lower – Gray requires final machining, it is not suitable for those seeking a drop-in, ready-to-assemble lower receiver without fabrication work. DIY builders with access to a jig and basic machining tools Gunsmiths constructing a custom AR15 from the ground up Enthusiasts seeking a non-serialized lower for personal build projects Shipping & FFL The RL556V3 80% AR15 Lower – Gray is classified as a non-firearm component and may be shipped directly to your residence without requiring transfer through a Federal Firearms License (FFL) holder. However, it is the purchaser's sole responsibility to verify that local, state, and federal laws permit the possession and completion of 80% lower receivers. This product must not be sold to or possessed by individuals prohibited from owning firearms. Once the receiver is machined to a functional state, it becomes a firearm subject to all applicable laws. We recommend retaining documentation of your compliance with ATF guidelines. No FFL is required for the purchase of this unfinished component. Ships directly to your address; no FFL transfer needed Buyer must confirm legality in their jurisdiction before ordering Upon completion, the receiver becomes a firearm subject to federal regulations
