About this product

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 thicker buffer tower eliminate the weak points of old polymer lowers. The flared magwell gets you faster reloads, and the threadless grip design means a rock-solid, no-wobble fit with our proprietary grips. It’s mil-spec where it counts, so your standard LPK and upper will fit right.

Your kit includes everything you need to finish the job: the white 80% lower receiver, our precision drilling jig, trigger hole guide, drill bits, and end mill. Just add your tools, time, and a standard AR-15 parts kit.

Kit Includes:

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

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