Caliber Compatibility Guide
Use the chart below to verify which calibers are supported by each GDM® suppressor family. Always follow minimum barrel length requirements and pressure class guidelines listed on individual product pages.
Important:
Caliber support does not override barrel length minimums, pressure class limits, or mounting requirements. Always confirm host configuration before firing.
All suppressors are backed by a lifetime defect warranty.

Important Compatibility Notes
Mounting System Matters
Most GDM® suppressors use the HUB (1.375×24) standard.
Ensure your chosen mount and muzzle device are rated for the same caliber and pressure class.
Barrel Length Minimums Apply
Short-barrel configurations dramatically increase pressure and heat.
Always verify minimum barrel lengths before firing.
Pressure Class Ratings
Some cartridges (e.g., .277 Fury, .300 Win Mag, magnum calibers) fall into higher pressure classes.
Only use these on suppressors explicitly rated for magnum / high-pressure use.
Endcap / Muzzle Nut Selection
For GDM® 30, 45, and 46 Series suppressors, always install the correct caliber-specific muzzle nut to avoid baffle or endcap strikes.
