RL556V3 80% AR15 Lower – Gray
Overview
The RL556v3 80% AR15 lower – gray represents a precision-machined platform for builders who require a reliable foundation without unnecessary ornamentation. Manufactured by RL556v3, this 80% lower receiver is designed to meet the specifications of the AR15 platform while giving the end user the flexibility to complete the fire control pocket and trigger channel according to their own quality standards. The gray anodized finish provides consistent corrosion resistance and a low-reflectivity surface suitable for both range and field use. As a component classified as a firearm part, this lower requires finishing before it can accept standard AR15 lower parts kits and buffer tube assemblies.
Features & Specs
Every RL556v3 80% AR15 lower – gray is machined from 7075-T6 aluminum billet, then hardcoat anodized in a uniform gray. The 80% configuration means the fire control cavity, trigger slot, and hammer pin holes are not fully milled, allowing the builder to complete these critical areas with standard jigs and tooling. The lower is compatible with all mil-spec AR15 upper receivers, buffer tubes, and pistol grip configurations.
- Material: 7075-T6 aluminum billet, hardcoat anodized gray
- Compatibility: Mil-spec AR15 upper receivers, LPKs, and stock systems
- Machining: 80% complete – fire control pocket and trigger channel require finishing
Who It’s For
The RL556v3 80% AR15 lower – gray is intended for individuals who prefer to complete their own firearm components using proper tools and techniques. This product is suitable for hobbyists, gunsmiths, and builders who have experience with 80% lower jigs and understand the legal requirements surrounding unfinished receivers. It is not a finished firearm and should not be purchased by those seeking a ready-to-assemble lower. The gray finish appeals to builders who want a subdued, non-black aesthetic that matches other gray or FDE components in a custom build.
