The WARP-15 is a monolithic, injection-molded polymer AR-15 style lower receiver manufactured from 30% glass-filled nylon and engineered to integrate the buttstock, buffer tube, pistol grip, and trigger as integral components. It is designed to pair with most common AR-15 uppers and standard mil-spec parts kits for a simplified build process. The design emphasizes reduced part count and lighter weight compared with similarly configured multi-piece lowers.
