The Diligent Defense Co Muzzle Device 1/2X28 is a precision-machined suppressor mount built for shooters running .30 caliber and smaller rifle cartridges. If you're building a suppressed rifle setup and need a rock-solid brake-to-can interface, this adapter handles the job with industrial-grade durability. It's engineered to work with major suppressor platforms—Q, Dead Air, Rugged, Surefire, and others that use the standard .900-24 mount pattern—so you're not locked into one can ecosystem.
Built from 17-4 stainless steel and heat-treated to H900 specification, this muzzle device delivers the kind of precision that matters when you're threading suppressors. Every critical alignment feature is machined in a single setup, which means no tolerance stack-up and no shimming required to get your can indexed right. The 360-degree port design eliminates the fiddling; just thread it on and go. At 1.9 ounces and 1.45 inches long, it adds minimal length and weight to your setup.
Installation and removal are straightforward with the 13/16-inch hex rear—any standard wrench gets the job done. You'll notice variation in the heat-treat finish across the part; that's normal in H900 treatment and purely cosmetic. It has zero effect on strength or performance. Whether you're suppressing a precision rifle for long-range work, a hunting build, or a range gun, this adapter is engineered to stay put and hold zero.
