Walther P22 Thread Adapter

The United Defense Walther P22 Thread Adapter converts your pistol's factory M8x.75 metric barrel threads to the industry-standard 1/2x28 TPI pattern, opening up compatibility with rimfire suppressors, compensators, and other .22 caliber muzzle devices. Precision-machined from steel with a durable black finish, it installs as a direct replacement for the factory muzzle nut — no gunsmithing required. A knurled thread protector cap is included to safeguard the threads when no device is mounted. Built for P22 owners who want to run a can, a comp, or any other 1/2x28 accessory without hunting down obscure metric hardware.

Features

    Installed in like 2 minutes, zero gunsmithing, threads are clean and it seats perfectly. Machined nice, finish matches the gun, and it even came with a little knurled protector cap for the threads.

    Got the Walther P22 thread adapter last week and it screwed on dead straight, no cross‑threading.

    Easy install, threads line up perfectly

    I installed this on my P22 at the range to run my suppressor and it threads right on replacing the factory nut no problem. Works good for attaching the silencer and keeps the gun balanced.

    Easy install on the barrel
    Lets me use standard 1/2x28 suppressors
