Suppressors….or silencers (whatever you’d like to call them) improve the safety of the shooter, improve the accuracy of your firearm, and are just plain fun to shoot.

If you’re looking for the best AR15 suppressor, we have something you need to take a look at.

Let’s take a closer look at the new Maxim Defense DSX-D Duty Suppressor for 5.56, 7.62, and 6.5 Creedmoor.

The DSX-D (Duty Suppressor System – Direct Thread) Suppressor

This suppressor is specifically designed to minimize the violent cyclic rate and gas blowback of a suppressed weapon system such as the AR-15.

The suppressor consists of a three-piece MonoKore design that adds 7.25″ to the muzzle of your rifle. The DSX-D is rated for full auto in all available calibers; 5.56mm, 7.62mm, and 6.5 Creedmoor.

There is, however, an 8.5″ barrel restriction.

Additionally, the suppressor can be pinned to a 10.3″ barrel to essentially give you a 16″ overall barrel length.
