PRS:338–HQD 

The PRS:338 HQD was built for shooters who want serious suppression performance without the added bulk and weight commonly found in large-caliber suppressors. Chambered for .338 caliber platforms and utilizing Maxim Defense’s Quick Detach mounting system, the PRS:338 HQD delivers lightweight handling, repeatable mounting performance, and the proven sound reduction benefits of M-Kore™ Technology in one refined package.

Designed for precision rifles, hunting applications, and semi-auto platforms, the PRS:338 HQD keeps rifles balanced and maneuverable in the field. Weighing just 19 oz and measuring 11” in length, it minimizes excess front-end weight while still providing substantial suppression performance for larger caliber systems.

Constructed with a 7075 aluminum core, 17-4 stainless steel module, and QD Mount, the PRS:338 HQD is optimized for lightweight, light-to-mid-duty use while maintaining durability where it matters most. Finished in Type III hard coat anodizing and rated for barrels 26” and longer, this suppressor is purpose-built for shooters seeking a lightweight, high-performance .338 suppressor solution.
