Spike's Tactical Calico Jack — Stripped Lower Receiver

Spikes Tactical Calico Jack Stripped Lower Receiver - AR-15

Give your next build a little personality without sacrificing quality — the Spike's Tactical Calico Jack Stripped Lower Receiver swaps the usual ST Spider logo for a distinctive Calico Jack pirate design, with "Parley," "Plunder," and "Arrr" selector markings in place of standard safe/fire engravings.

Underneath the themed engravings, this is a genuine Spike's Tactical lower built to the same standards their receivers are known for: CNC machined from a 7075 T6 MIL-H-6088 forging for real strength and precision, with a MIL-A-8625F Type III Class 2 hard coat anodized finish inside and out for lasting durability. The multi-caliber design accepts .154" diameter trigger and hammer pins, giving you flexibility across a range of AR-platform builds, and the low-shelf design is RDIAS compatible for those pursuing that configuration.

At just 8.6 oz, this stripped lower gives you a solid, precision-machined foundation to build from — pair it with your choice of lower parts kit, buffer, and stock to complete the build exactly how you want it. Since it ships stripped, you have full control over every component that goes into your rifle rather than being locked into a pre-assembled configuration.

Whether you're starting a themed build, want a genuine Spike's Tactical lower with some added character, or are simply stocking up on quality stripped lowers for future projects, the Calico Jack gives you real build quality with a distinctive look that stands out from a standard black lower.

Note: This is a stripped lower receiver only. Requires a lower parts kit, buffer, and stock of your choosing to complete. All firearm sales are subject to a completed background check and applicable federal, state, and local laws. In-store purchase or FFL transfer required.
