GDM® 30C Rifle Suppressor

The GDM® 30C is part of the GDM® 30 Series — a modular suppressor platform designed to balance sound suppression, durability, weight, and mounting flexibility.

Manufactured entirely in-house at our family- and veteran-owned facility in Dayton, Ohio, the 30C is built for shooters who demand uncompromising quality in a compact form factor.

At just 5.75 inches long and 10 ounces, the 30C minimizes added length while maintaining effective suppression across .30 caliber platforms. The HUB (1.375×24) interface ensures compatibility with leading mounting systems without locking you into proprietary hardware.

Independent third-party testing validates the GDM® 30 Series’ real-world performance.

Engineered for Durability & Performance

Constructed from fusion- and laser-welded 6Al-4V Grade 5 titanium, the 30C delivers exceptional strength at minimal weight. A DLC coating internally and externally enhances hardness and corrosion resistance for demanding use.

The 30 Series is offered in multiple lengths to support different mission profiles. The 30C is optimized for shooters prioritizing compactness and balance.

Interchangeable Muzzle Nut System

The GDM® 30 Series features an interchangeable muzzle nut system that allows caliber-specific optimization.

  • Allows serviceability in the event of an end-cap strike
  • Includes .30 caliber muzzle nut (additional sizes available for purchase)
  • Removable using the included wrench
  • Also includes 5/8 x 24 direct thread mount (additional sizes available for purchase)

This system provides flexibility, longevity, and serviceability without compromise.
