M5 Long Action Floor Plate Compatibility Explained: CIP vs. Standard Mag Lengths

Understanding M5 Long Action Floor Plate Compatibility 

When building a precision rifle or upgrading your current setup, magazine compatibility is a key consideration—especially for long action cartridges. In a recent breakdown, Steve from Grayboe explains how the M5 long action floor plate stands out for its dual compatibility with both CIP-length and standard long-action magazines. 

The key measurements to keep in mind: 

- Standard Long Action Magazines: 3.715" (e.g., .30-06) 

- CIP-Length Magazines: 3.850" (e.g., .300 PRC) 

The M5 long action floor plate from Grayboe supports both these lengths, meaning you can confidently run a variety of long-action rounds without changing hardware. Whether you're chambering a .30-06 or stepping up to a .300 PRC, this floor plate has you covered. 

For rifle enthusiasts and gunsmiths alike, this compatibility eliminates guesswork and expands your build possibilities.
