I have not. I'll look around and see if I have any at home in a
.25. I've shot mainly JSB kings and they have been great.
The gun has a Huggett on it and is so quiet. More than backyard
friendly. If you want one with the Huggett I was told you have to
order it at the same time or return the gun to have one added later.
Nothing to do with installation, just screws on the existing shroud cap.
Probably some regulation.
Here's a link to my first impression of the gun.
