RL556v3 80% AR15 Lower – White

Polymer80 RL556v3 80% Lower – White

Build it right. Build it light. This isn’t your average 80% lower. Polymer80’s RL556v3 in White is engineered from the ground up with our reinforced polymer composite. The solid core design and beefed-up buffer tower give you a rigid foundation you can trust.

We built it for function. The flared magwell makes reloads smooth, even under pressure. The threadless grip area is a P80 exclusive—it eliminates alignment headaches and gives you a clean, solid mount for your preferred grip.

Everything you need to finish the job is in the box: the white 80% lower receiver, our precision polymer jig, trigger hole drill guide, drill bits, and end mill. Just add your tools, parts kit, and focus.

For under a hundred bucks, you get a proven platform to start a truly custom AR-15 build. Choose White for a clean, modern look or to serve as a perfect base for cerakote. It’s a straightforward, no-nonsense way to own your build from start to finish.

Available Colors: Black, White, FDE, OD Green, Gray.
