If you want to mount any 1/2x28 TPI threaded accessories
on your Walther P22 handgun, such as a suppressor, a
flash hider, or a fake suppressor, this is the part that
you need. This thread adapter easily replaces the factory
barrel nut using Walther's factory supplied barrel
wrench and works equally well on 3.4" and 5" guns.
(However, it will not work on non-threaded guns.)
The Walther P22 Thread Adapter is CNC manufactured to
precision tolerances from solid steel rod in one CNC
lathe operation to ensure exact thread alignment and
are hot salt blued to match your P22 pistol. Each retail
packaged adapter assembly consists of one adapter and
one knurled OD thread protector.
