About this product

Polymer80 RL556v3 80% Lower Receiver – White

Build it right. Build it light. This isn’t just another white 80% lower. This is the Polymer80 RL556v3, engineered from the ground up to fix the weak points of traditional polymer receivers. We run these on our own range guns.

The heart of it is the solid-core composite design and that reinforced buffer tower. It handles mil-spec components and standard carbine buffers without a hitch. The flared magwell makes reloads fast, and the integrated, threadless pistol grip means a rock-solid fit with no slop.

Your kit comes with everything you need to finish the job: the white 80% lower, our precision polymer jig, drill guide, and the correct drill bits and end mill. You supply the tools, the time, and the final pride of ownership.

Complete RL556v3 Kit Includes:

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

Available in Black, White, FDE, OD Green, and Gray.

Price: $97.99
