SilencerCo Delta 1/2"-28 Thread Adapter for Walther P22 - Steel Matte Finish

The SilencerCo Delta 1/2"-28 thread adapter for Walther P22 turns your rimfire pistol into a suppressor-ready host in seconds. If you're running a dedicated 22 silencer—whether it's a Switchback, Sparrow, Spectre, Warlock, or Osprey Micro—this steel adapter threads directly onto your P22's muzzle and provides a clean, stable platform for suppressor mounting. The o-ring engagement design keeps your muzzle threads protected from fouling and ensures your silencer stays locked in place through firing sequences.

This is the kind of simple, effective accessory that serious 22 shooters rely on when they want to keep suppressors mounted across multiple firearms. The matte steel finish resists corrosion and blends with the pistol's profile. Installation is straightforward—no gunsmithing required—and removal is just as quick if you need to switch hosts or clean.

Whether you're suppressing subsonic rounds at the range, hunting small game quietly on your property, or just looking to tame the report on a fun shooter, the Delta adapter bridges the gap between your Walther P22 and any compatible SilencerCo 22 suppressor.
