Billet Armory is a Texas-based boutique firearms customization and precision machining shop specializing in high-end performance upgrades for modern pistols. We focus on optic cuts, slide milling, barrel threading, porting, Cerakote finishes, and custom 2011 builds and modifications, all completed in-house with meticulous attention to detail.

Every firearm we work on is treated as an individual project—not a production job. From direct-mill red dot optic cuts on OEM slides to advanced slide modifications and custom finishes, our process emphasizes tight tolerances, proper fitment, and real-world reliability. We do not outsource critical machining—each cut, thread, and finish is performed under our direct control.

Billet Armory is trusted by shooters who value precision craftsmanship over volume, whether for duty use, competition, or range performance. Our custom 2011 work and firearm modifications are designed to enhance function, durability, and aesthetics without compromising safety.

Proudly operating in Texas, Billet Armory delivers high-end firearms customization, built for shooters who demand performance, consistency, and uncompromising quality.
