Spike's Tactical Spartan — AR-15 Platform Stripped Lower Receiver

Spikes Tactical Spartan Stripped Lower Receiver - AR-15

Build your next AR-15 platform rifle with a lower that looks as disciplined as it performs — the Spike's Tactical Spartan Stripped Lower Receiver swaps the usual ST Spider logo for an iconic Spartan Helmet design, giving your build a distinctive look without compromising on Spike's build quality.

This is a genuine Spike's Tactical lower for the AR-15 platform, CNC machined from a 7075 T6 MIL-H-6088 forging for real durability and precision, finished with a MIL-A-8625F Type III Class 2 hard coat anodized finish inside and out for a resilient, premium look that holds up to real use. Fine milled manufacturer engravings add to the aesthetic without cutting corners on the underlying build quality Spike's is known for. The multi-caliber design accepts .154" diameter trigger and hammer pins, giving you flexibility across a range of AR-15 platform builds, and the low-shelf design is RDIAS compatible for those pursuing that configuration.

Since it ships stripped, you retain full control over every component in the finished rifle — pair it with your choice of lower parts kit, buffer, and stock to complete the build exactly how you want it, rather than being locked into a pre-assembled configuration.

Whether you're building a themed AR-15 platform rifle to match your training philosophy, want a genuine Spike's Tactical lower with some added character, or are simply stocking up on quality stripped lowers for future projects, the Spartan gives you real build quality with a design that stands apart 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.
