The Wraithworks WARP-15 Polymer Stripped Lower Receiver (part no. WARP15-BLK-S) takes a different approach to the AR-15 lower, molding it as one monolithic piece from glass-filled nylon instead of machining it from aluminum. The receiver integrates the buttstock, buffer tube, and pistol grip directly into a single injection-molded unit, drawing on earlier monolithic polymer receiver designs while adding modern manufacturing refinements. The stripped designation here means it ships without a fire control group, not without a stock; the WARP-15 is compatible with mil-spec fire control groups as well as cassette-style match triggers. For shooters looking to shave weight and part count off a build, the WARP-15 is a distinctive one-piece option.
