RL556v3 80% AR15 Lower – White

Polymer80 RL556v3 80% Lower – White

Price: $97.99

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 cheap copy; it’s an improvement.

The core is solid. The magwell is flared for faster reloads. The buffer tower is the thickest we’ve ever made to handle thousands of rounds. We also ditched the grip screw threads for a cleaner, stronger grip interface that eliminates a common stress point.

Your kit includes everything you need to finish it right: the white 80% lower, our precision polymer jig, a trigger pin drill guide, drill bits, and the end mill. The jig is key—it’s simple and gets the job done without fuss.

Available in Black, Flat Dark Earth, OD Green, and Gray. The White finish is perfect for a unique custom build or a clean base for cerakote.

Kit Includes:

• 80% Polymer AR-15 Lower Receiver (Mil-spec)
• Polymer Jig
• Trigger Hole Drill Guide
• Drill Bits and End Mill

Note: Requires machining to complete. Familiarity with tools and local laws is required.
