Wraithworks WARP-15 Polymer Complete AR-15 Lower | FDE

The Wraithworks WARP-15 is a monolithic polymer AR‑15 style lower receiver molded from injection‑molded 30% glass‑filled nylon that integrates the buttstock, buffer tube, pistol grip and trigger area into a single component. This integrated design reduces parts count and overall weight compared with comparable multi-piece lowers while retaining compatibility with common AR‑15 upper receivers. The WARP-15 ships as a complete lower with a Mil‑Spec parts kit and features a flared magwell, aggressive grip texture and an injection‑molded buttplate with a trap door.

Suitable applications include range training and recreational target shooting, and lightweight field or caliber‑specific builds such as 9mm PCC or suppressed .300 Blackout projects when paired with the appropriate upper and buffer system. The design emphasizes durable polymer construction and compatibility with a wide range of mil‑spec fire control groups and aftermarket cassette triggers.
