The Spike’s Tactical upper and lower receiver set in FDE Cerakote (brand part no. STS1512) gives you a matched pair of forged receivers to build a rifle on. Spike’s Tactical finishes the set in FDE and marks the lower with the Spider logo and bullet pictogram selector markings. The forged 7075-T6 upper includes a forward assist and ejection port door, and the lower is a multi-caliber, low shelf, RDIAS compatible design. It suits a builder who wants the color settled before the first part is installed.
