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.
