The RL556v3™ features Polymer80’s proprietary polymer composite, a solid core design, flared magwell, and heavier mil-spec buffer tube housing. The pistol grip area features a unique threadless design specific to Polymer80 rifle lowers. The RL556v3 brings a fresh design aesthetic and incorporates more reinforced areas along the magwell and fire control pocket. With the addition of the blank serialization plate to the right side of the receiver blank above the magwell, customers who are required to apply a serial number can legally do so.

The kit includes:

  • 80% Polymer AR15 Lower Receiver (Mil-spec)
  • Polymer Jig
  • Trigger Hole Drill Guide
  • Drill Bits and End Mill
  • Serialization Plate
