The RCBS .223 Remington Chamber Case Length Gauge (SKU: R88280) is a precision-machined tool designed to verify both chamber dimensions and case length on your reloaded ammunition. Whether you're reloading for hunting, competition, or tactical applications, this gauge helps ensure every .223 round you produce meets critical safety and performance standards.
Constructed from hardened steel for durability, the RCBS gauge allows you to check headspace, shoulder setback, and overall case length in one quick step. Simply insert a resized or loaded round — if it fits flush, you're good to go. If not, it highlights cases that are over-length or improperly sized, preventing feeding issues or pressure problems in your firearm.
Trusted by reloaders around the world, this tool is especially valuable when working with semi-automatic rifles where proper case dimensions are vital for function and reliability. A must-have for any serious reloader working with .223 Rem or 5.56 NATO rifles.
