RL556v3 80% AR15 Lower – Gray
The RL556v3 RHINO Gray is the exact same forged 7075-T6 monster that dominates the 80% market — now professionally finished in factory-applied Titanium Gray (H-170) Cerakote, the perfect wolf-gray / battleship-gray shade that’s blowing up on Instagram and tactical builds nationwide.
Every Gray RL556v3 lower features:
- Forged 7075-T6 aerospace aluminum (30–40% stronger than 6061)
- Factory H-170 Titanium Gray Cerakote – oven-cured, 0.001–0.0015″ thick
- Threaded bolt catch pin hole (1/4-28 – no roll pin)
- Fully broached & flared magwell
- Deep laser-engraved FIRE / SAFE markings (engraved BEFORE Cerakote = zero fill-in)
- Integrated oversized trigger guard
- Dead-on color match to Magpul Stealth Gray, Aero Titanium, and most modern “gray” furniture
No jig included — perfect for builders who already own an Easy Jig Gen 3 and want the single most requested custom color without the DIY hassle or $150+ coating bill.
