SilencerCo Delta Thread Adapter 1/2"-28 for Smith & Wesson M&P 22 Compact - Steel Matte Finish

If you're running a Smith & Wesson M&P 22 Compact and want to add a suppressor to your .22 setup, the SilencerCo Delta Thread Adapter makes the conversion straightforward. This 1/2"-28 thread adapter bridges your M&P 22 Compact's factory 3/8" x 24 muzzle threads to the standard 1/2" x 28 suppressor mounting interface, letting you attach any SilencerCo .22 can in seconds. The steel construction with matte finish resists corrosion and blends with modern M&P aesthetics.

The real advantage here is the o-ring engagement design. Those o-rings do more than just sit there—they keep your muzzle threads clean and prevent your suppressor from loosening under the vibration and recoil of repeated fire. That's the kind of attention to detail that separates a solid adapter from one that leaves you wondering if your can is going to stay put. If you're running a Switchback 22, Sparrow 22, Spectre 22, Warlock 22, or Osprey Micro 22, this adapter gives you the reliable mounting interface each of those cans expects.

This is a no-fuss solution for .22 shooters who want their rifle ready for suppressed shooting without gunsmithing or permanent modifications. Drop it on, thread your can, and you're ready to enjoy the benefits of a quieter .22 at the range or in the field.
