Vulcan end cap removal ?

As Chiro said, we'll need to know which version of the Vulcan you have. If you have one of the earlier versions without the knurled end-cap that unscrews, you'll need something like a pair retaining clip pliers to unscrew the end-cap. Once that is un-screwed, John Hagan (and others) makes an adapter that you can screw into the shroud that will allow you to add a moderator.

If you have a .22, I have an extra Hagan adapter that I could sell you if you want it.

Thanks. Needle nosed pliers worked for me.
