*DSX QD suppressor from Maxim Defense, flexibility without sacrificing performance*

Logan Windfieldt with Maxim Defense Giving GunBroker the First Look at the Maxim Defense DSX QD and DSX-D Suppressors during CanCon 2024 Arizona

The DSX QD suppressor from Maxim Defense builds on the proven DS platform with added versatility. Featuring a new QD (quick-detach) mount and proprietary muzzle devices, it’s designed for easy attachment and removal—thanks to a reverse-thread system that prevents carbon lock and keeps the taper clean. Even better, it’s cross-compatible with muzzle devices from CGS and Spectre, using the same thread pitch. It offers the same compact size and weight as the standard DS suppressor, making it a seamless upgrade for users who want flexibility without sacrificing performance.
