Introducing the GDM™ 30M Rifle Suppressor (part of the new GDM™ 30 series) from Guardian Defense Mfg, proudly crafted in our Dayton, OH family/veteran-owned facility.

The new GDM™ 30 series suppressors are designed to provide industry-leading sound suppression, lightweight, affordability, and compatibility with various mounting systems. The suppressors have been independently tested by a 3rd party source to ensure objective data.

The GDM™ 30 series comes in three different lengths to cater to different applications: short, mid-length, and long. This gives the end user the flexibility to choose the optimal sound suppressor for their specific needs. Moreover, the suppressors are made using high-quality materials to ensure durability and performance.

One of the key features of the 30 series is the innovative Interchangeable Muzzle Nut. This feature allows users to optimize the suppressor’s performance based on the caliber they are shooting. The package includes a 30 Cal Muzzle Nut, and additional muzzle nuts for calibers like 6.5, 5.56, and 6.0 can be purchased separately. The caliber nut can also be removed using the included wrench, providing the end user the ability to repair their suppressor in the event of an end cap strike.

The GDM™ 30 series is constructed from Fusion Welded 6Al 4V Grade 5 Titanium, which ensures strength and durability while keeping the weight in check. The weights of the different models are as follows: GDM™ 30K weighs 11.5oz, GDM™ 30M weighs 15oz, and GDM™ 30L weighs 18.5oz. The lengths of the suppressors are as follows: GDM™ 30K is 6.45” long, GDM™ 30M is 8” long, and GDM™ 30L is 9.5” long. The diameter of the suppressors is 1.612 inches.

Guardian Defense Mfg takes pride in manufacturing the GDM™ suppressors in their family/veteran-owned facility in Dayton, Ohio. This ensures that every aspect of the suppressor, from design and manufacturing to welding and final packaging, is achieved with a focus on delivering innovative products with rock-solid dependability, all proudly made in the USA. The suppressors also come with a lifetime defect warranty, providing additional peace of mind to the customers.
