The Lead & Steel LLC LSQGB-625 is a .625" nitride steel component built for builders and gunsmiths who demand precision parts and reliable metallurgy. If you're assembling or servicing firearms and need a quality steel component that can handle repeated use and tough conditions, this piece delivers the durability you'd expect from nitride-treated steel—a finish that resists corrosion and wear while maintaining dimensional accuracy.
Nitride steel offers a practical advantage over bare steel: it's harder on the surface, resists rust and oxidation, and holds its finish under field conditions. That makes this Lead & Steel component suitable for critical applications where you can't afford dimensional drift or corrosion-induced wear. Whether you're building a precision rifle, replacing a worn part, or stocking your gunsmith workbench, the nitride treatment gives you confidence that the part won't degrade in storage or during use.
Lead & Steel LLC specializes in quality steel components for the firearms industry, and this .625" piece reflects that focus on material science and manufacturing standards. If you work on guns—whether as a professional gunsmith, a serious hobby builder, or an armorer—you recognize that the small parts matter as much as the major assemblies.

Nitride is a surface hardening process that increases wear resistance and corrosion resistance compared to bare steel. For firearms components, this means longer service life, better dimensional stability, and reduced maintenance in the field.
