Spike's Tactical Spider Stripped Lower Receiver

Spike's Tactical's Spider stripped lower is a forged 7075-T6 mil-spec receiver that trades anonymity for a recognized name and the brand's signature spider engraving. Dimensionally it is standard mil-spec: it accepts any AR-15 upper, any lower parts kit, and any standard trigger group, so it drops into a build with zero fitment surprises. The Type III hardcoat anodized finish meets the same MIL-A-8625F spec used on duty-grade receivers.

The Spider carries a low shelf, which keeps it compatible with registered drop-in auto sears for the holders who care and is otherwise irrelevant to a standard semi-automatic build. Selector markings use Spike's bullet pictograms rather than text. Spike's backs the receiver with a lifetime warranty, which separates it from clearance no-name forgings at a similar price.

For a builder who wants a step up from a bare bargain lower without paying for billet or integrated ambi controls, the Spider is the value-to-mid anchor: real brand, real warranty, standard mil-spec function.
