Wraithworks WARP-15 Polymer Complete Lower | Integral Buttstock

The WARP-15 is a monolithic, injection-molded polymer AR‑15 style lower receiver that integrates the buttstock, buffer tube, pistol grip, and trigger area into a single component. This integrated construction reduces weight and parts count compared to conventional lowers while maintaining compatibility with common AR‑15 uppers and mil‑spec parts. The design includes an A1-length stock with a 13-inch length of pull, M‑LOK slots and QD socket holes, a textured Wraithworks pistol grip, and an injection-molded buttplate with a trap door.
