I'd really like to go the SBR/SBS route, but the fact that you can't transport them across state lines without an ATF permission slip makes it a pain in the butt more than I care to deal with. That plus the small but possible chance of me needing to move to a non-NFA state someday. My SUB-2000 is my dedicated carry gun for when I visit family in upstate NY, of all things

Yep, perfectly legal. Texas doesn't have a concealed weapons law like most states; the only reason we deal with it with handguns is that §46.02 prohibits carrying a handgun at all, and a CHL then in turn legalizes you carrying a handgun concealed. Firearms other than handguns can be carried loaded, unloaded, openly, concealed, or taped to your forehead like you're playing Injun Poker. Just don't threaten people with it, don't go to a location prohibited by §46.03, and you're golden.

Incidentally, I too have a SUB-2000 which tags along with me in a messenger bag on trips and lives in a locked and secured-to-the-frame case in the truck when I'm not on a trip. It's a handy rifle to be sure!
