GDM® 22AL Rimfire Suppressor

The GDM® 22AL is part of the GDM® rimfire series — offering a dedicated, lightweight suppressor solution for shooters focused on .22 LR performance and affordability.

Manufactured entirely in-house at Guardian Defense Mfg’s family- and veteran-owned facility in Dayton, Ohio, the 22AL reflects the same attention to quality and consistency found across the full GDM® suppressor lineup.

At 5.6 inches long and just 4.2 ounces, the GDM® 22AL minimizes added weight and maintains excellent handling on both pistols and rifles. Its dedicated .22 LR rating ensures consistent suppression performance for recreational shooting, training, and high-round-count use.

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

Engineered for Affordable Rimfire Performance

The GDM® 22AL is constructed from 6061 aluminum tubing with 7075 aluminum baffles, balancing durability, performance, and cost efficiency. A hard-coated anodized finish provides corrosion resistance and long-term protection.

Designed specifically for .22 LR, the 22AL offers a straightforward, reliable suppressor solution without unnecessary complexity.

Lightweight Handling & Dedicated .22 LR Use

The GDM® 22AL is designed to preserve natural handling characteristics on rimfire pistols and rifles by minimizing forward weight and maintaining consistent balance. Its lightweight aluminum construction reduces fatigue during extended range sessions while keeping point-of-aim shift to a minimum.

Optimized specifically for .22 LR, the 22AL delivers predictable, repeatable suppression performance without the added complexity of multi-caliber designs. This makes it an excellent choice for training, recreational shooting, and high round-count use where simplicity, reliability, and affordability are key priorities.
