Airgun Technologies I Was Out, But They Keep Bringing Back In...

Hi Guys & Gals, been out of the game for awhile, but the fever never quite went away. I lost interest because I stopped hunting & Grandkids seem to replace it.
Anyway, I have a 2-part question:

1st, I don't really like bullpups, but love carbines, so;
Is there a way to turn a Vulcan (1st rendition) into a carbine; stock choices of course.
It's a wonderful rifle but not my bag. If the answer is no then I'm afraid it will have to go on the block.

2nd, whether I sell or keep, I want to get it re-sealed;
I would like to get in touch with Derrick Wall, but can't seem to get a callback on the number Charlie Frear gave me
Does he have a website or business name I should be looking for?

Thanx in advance
