RL556v3 80% AR15 Lower – White

Polymer80 RL556v3 80% Lower Receiver – White

Price: $97.90

This is the RL556v3, our latest and toughest 80% AR-15 lower. We built it from the ground up with our reinforced polymer composite. It’s not a copy of an aluminum lower; it’s engineered for polymer.

The solid-core design and reinforced buffer tower handle a standard rifle setup without issue. The flared magwell makes reloads fast, and the threadless grip system is a Polymer80 exclusive—your grip screws directly into steel inserts for a rock-solid fit that won’t strip.

Your kit includes everything you need to finish the job: the white 80% lower, our precision polymer jig, a trigger hole drill guide, drill bits, and the end mill. It’s a straightforward build.

This lower is available in five colors: Black, White, FDE, OD Green, and Gray. The White finish is clean and perfect for a custom, standout build.
