SilencerCo Delta Adapter for Walther P22

The SilencerCo Delta Adapter for the Walther P22 (brand part number AC5) adapts the pistol’s M8x.75 muzzle threading to the more common 1/2×28 pattern, getting the host suppressor-ready in seconds. SilencerCo’s O-ring engagement design keeps muzzle threads clean and helps prevent a suppressor from working loose during firing, a common frustration with direct-thread mounting on rimfire hosts. Because the P22’s factory threading isn’t the industry-standard 1/2×28, this adapter is the correct way to run a compatible suppressor on the pistol without machining the barrel. It’s compatible with SilencerCo’s Switchback 22, Sparrow 22, Spectre 22, Warlock 22, and Osprey Micro 22, giving Walther P22 owners a quick path to running those cans.
