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

    Threaded right onto my barrel with no drama and the flats let me snug it down with a small wrench. Ran about 200 rounds of bulk Federal through it with my suppressor and it stayed put the whole time. Thread protector is a nice touch for when I'm just plinking without the can. Concentric to the bore as far as I can tell, groups didn't open up at all.

    Comes with thread protector

    Wish it came in stainless not just black

    Simple part that does exactly what its supposed to do. Converts the P22 threads to standard 1/2x28 so you can run a suppressor. Great job and even better price!

    Quality seems really good.

    I wanted to run a silencer for my Walther P22 and so ordered the threaded adapter. It fit perfectly with a simple installation and my silencer fit on snugly. The finish matched the rest of the pistol and so I am totally happy with my purchase.

    Easy of installation and worked as advertise3d.

    This is exactly what you need if you want to run a 1/2x28 suppressor on the P22. Took me like 30 seconds to install, screwed my Dead Air Mask on and went to the range. Three mags of CCI Quiets and I was grinning ear to ear. Customer service at Keep Shooting was also really helpful when I had a question about compatibility before ordering.

    Simple installation
