Luth Gunsmith Parts Kit

The Luth Gunsmith Parts Kit is purpose-built for gunsmiths, AR armorer shops, and serious home builders who need a reliable assortment of common replacement components on hand. This kit consolidates small parts that consume time sourcing individually—detent springs, roll pins, selector components, and buffer tube hardware—into a single organized package.

Whether you're running a professional shop or managing a personal build bench, having these components pre-stocked eliminates downtime and keeps projects moving forward. Each component is selected based on frequency of use in both new builds and repair work, ensuring that whatever you encounter—a worn detent, broken spring, or missing pin—you have a replacement without waiting for a supplier.

Professional gunsmiths benefit most from this kit's inventory approach, as it reduces parts inventory complexity and cuts customer wait times for routine maintenance. Home AR builders—especially those assembling multiple rifle configurations—find immediate value in having backup components for common failure points.
