to buy a tax stamp as that appears to fall into the 'sawed off' catagory for barrel length.

Hey Samd I had found right after I posted this when I first got on the the site. It was a lot and I didn't know where to begin but that right there would be so nice to have. But what I would really like to do is mount one of those onto my SKS sporter. To answer your question NO I am not related to snake

Billy in Predator had a similar setup, although not NFA since it had a standard-length barrel.
Regardless of CDI factor, if I ever pay $2k for a shotgun somebody smack me in the head.
FYI if you intend to use any shotgun for door breaching, then a standoff device on the muzzle is a must-have in my book.
