Lym Pro Stainless Headspace Gauge 223Rem
The Lyman Pro Stainless Headspace Gauge for .223 Rem is a precision instrument built for handloaders and gunsmiths who need accurate, repeatable cartridge measurements. Whether you're setting up new sizing dies, verifying existing tooling, or troubleshooting ammunition dimensions, this stainless steel headspace gauge delivers the precision required for safe, consistent loads. The .223 Rem chambering makes it essential for AR platform shooters and small-caliber rifle hunters who load their own ammunition.
Stainless steel construction protects against rust and corrosion over years of shop use, while the tool's flat exterior sides prevent it from rolling across the bench. Integrated o-rings provide a secure, non-slip grip during use—a practical detail that makes repeated measurements faster and more comfortable. The gauge checks both maximum and minimum headspace dimensions, plus maximum case length, giving you three critical measurements from a single tool.
Headspace gauges are particularly valuable when setting up bottleneck cartridge sizing dies, as even small headspace errors compound across loaded batches. The Lyman Pro design reflects decades of handloading tool refinement and outperforms entry-level gauges with its stainless finish, ergonomic features, and multi-function capability. This is the right choice if you take your handloading seriously and want equipment that matches the precision of your dies and brass.
