A silencer adapter for S&W 422, 622 and 2206

Our silencer adapter for S&W 422, 622 and 2206 is a rarity in itself. While Smith & Wesson no longer produces these excellent pistols for over 20 years, many sports shooters still own one. Unfortunately, the adapter to mount a suppressor on it is now impossible to get… or is it ?

Yet mounting a silencer on these pistols is a natural wish. Because of the fixed barrel mounted low in the frame, the accessory fulfills its mission without obstructing your sights. An advantage that allows you to keep your results intact, while enjoying more discreet shoots.

Compatibilities of this silencer adapter

This custom part is intended to replace the original barrel nut. To this end, a 16 mm hexagon allows a good tightening (within reason of course). The original 11/32×48 TPI thread of the pistol is transformed into 1/2 UNF or 1/2 UNEF threads (to choose from).

Remember that the 1/2 UNF thread (also known as 1/2×20 TPI) is the European standard for .22 LR silencers. On the other hand, the 1/2 UNEF thread (also known as 1/2×28 TPI) is the American standard for the 22 caliber silencers in the broadest sense. So choose the one that it will be easier to find a silencer for in your country.

This model fits the original Smith & Wesson 422. But it fits the Smith & Wesson 622 and the Smith & Wesson 2206 too, its two most popular variants.

A quality custom part

We manufacture these silencer adapters for S&W 422, 622 and 2206 on modern CNC machines. They are made of XC38 steel (also known as C35) ensuring durability and concentricity. The adapter is then blued for optimal corrosion protection.

We are proud to enable discreet shooting with these excellent Smith & Wesson pistols. Far from being obsolete, they can benefit a second youth and find their way back to the shooting range. A favor that many other models deserve. If you have any suggestion to submit, please contact us !

    Wanted to find a better adapter for my S&W 422. There aren’t many available and the one I was using seemed cause serious problems with POI with the suppressor.
    This one has worked out fully as expected. Shipment, even though international, was much faster than I’d expected. I’m very pleased with the product and order handling.
