GDM® RFC Rimfire Suppressor

The GDM® RFC is part of the GDM® rimfire series — a suppressor platform designed to deliver dependable sound suppression across a wide range of rimfire calibers while maintaining a compact, lightweight form factor.

Manufactured entirely in-house at Guardian Defense Mfg’s family- and veteran-owned facility in Dayton, Ohio, the RFC reflects the same precision manufacturing standards used across the entire GDM® suppressor lineup.

At 5.6 inches long and just 4.6 ounces, the GDM® RFC minimizes added weight and length, making it well-suited for both pistols and rifles. Its multi-caliber rating allows a single suppressor to support multiple firearms, simplifying ownership without sacrificing performance.

Independent third-party testing validates the GDM® Rimfire Series’ performance, ensuring objective data and real-world confidence.

Engineered for Lightweight Rimfire Performance

The GDM® RFC is constructed from fusion- and laser-welded 6Al-4V Grade 5 titanium, offering an excellent balance of strength and weight. A DLC finish externally and S-Line coating internally provide corrosion resistance and easy cleaning for long-term use.

Rated for:

  • .22 LR
  • .22 WMR
  • .17 HMR
  • 5.7×28

The RFC is built to support a wide variety of rimfire applications with consistency and reliability.

Balanced Handling & Host Versatility

The GDM® RFC is engineered to maintain natural firearm balance across both pistol and rifle platforms. Its lightweight titanium construction minimizes front-end mass, reducing point-of-aim shift and preserving handling characteristics during extended shooting sessions.

This balance-focused design makes the RFC an ideal choice for shooters who frequently move between hosts and calibers while expecting predictable performance and repeatable results.
