The Spikes Tactical Calico Jack stripped lower receiver (part no. STLS016CFA) is a special-series lower marked for multi-caliber use, featuring the Calico Jack pirate logo in place of the usual ST Spider design and Parley, Plunder, and Arrr selector markings finished with color fill. Sold stripped, it ships with no internal fire-control parts installed, so you supply a lower parts kit, buffer, and stock of your choosing to complete the build.
