I have no experience with Wolf Airguns, but I checked their site and what they had to offer..
It reminded me of another site who I actually have used before, and I had really nice results with everything..
I needed a temp suppressor to fit On a barrel and In a shroud, and they had exactly what I was after..
Nice price, nice quality, and quick shipping. The site/url is:
http://www.tko22.com/ Others here would probably vouch for them too, as they're popular w/ the Benjamin / Crossman crowd.
If you're looking for 'the best', as mentioned above.. You Can Not Beat DonnyFL.
He's a great guy, and his products are outstanding in both function and quality. Highly Recommended!
Donny's site/url is:
https://donnyfl.com/ He has over the barrel, and shroud compatible 'adapters' for just about every popular make/model airgun,
as well as a full line of suppressors, and accessories. Airgun-Industry standard thread type [1/2-20]
so the conversion would allow for his or any other brand's suppressors to be mounted also.
