About this product

Polymer80 RL556v3 80% Lower – White

Price: $97.99

This is the RL556v3, our latest and most durable 80% AR-15 lower. We built it based on real user feedback. The core is solid polymer composite, so it’s tough where it counts. We added a flared magwell for faster reloads and reinforced the buffer tower area to handle a standard mil-spec buffer tube without worry.

The pistol grip area uses our threadless design. This means no tiny screws to strip or lose—your grip attaches securely and stays put. It’s a cleaner, more reliable system.

This Complete Kit Includes:

  • One White 80% Polymer Lower Receiver (Mil-spec)
  • Precision CNC-Machined Aluminum Jig
  • Trigger Pin Drill Guide
  • Required Drill Bits & End Mill Tool

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

You get everything you need to finish a functional, reliable lower. This is a straightforward project for anyone comfortable with basic tools and following instructions. Build it right.
