Thinking about getting an AR "sport utility rifle", for hunting and other self defense purposes, I want a varminter style hunting rifle w/scope, and a registered SBR upper. Should I get 2 lowers or are the tolerances close enough to allow switching without sighting back in. (I know that the lower is the only part that gets registered)

A registered AR15 SBR [i]lower receiver[/i] can have any length barrel on it, there are no registered uppers.

A zeroed upper remains zeroed when put on any lower receiver.

A registered SBR is not exempt from the 1994 Crime Bill and can't have any "evil features" unless it's also a grandfathered, legal semiautomatic assault weapon (aka pre-ban).

Since a dedicated varmint or match rifle needs no evil features having it on it's own lower isn't that expensive, you may have all the parts in your parts box other than the $170 upper receiver.

Chuck-
actually I have no parts box, yet, but was planning on getting a preban lower reciever registering it as an sbr, and going from there.
Are there any legal issues with having 2 lowers, 1 unreg. & 1 SBR, and more than one short barreled upper?

There are no legal problems on short barrels as long as you have at least one SBR lower and a complete assembly for the non-SBR lower.  That is at least one non-SBR upper.

Why SBR?  14.5" is plenty short enough and with a Vortex flash supressor, which you'll want anyway, the barrel is over the 16" NFA requirement.  You have to have permission to take a NFA weapon across state lines.

I want a SBR for the compact size (truck gun). About the permission, does that apply to an AOW as well?

Yes, you have to submit a form way ahead of time if you plan to transport ANY NFA item across state lines, and you must have the approval back before you do so.

Presto --

Are you aware of the terminal ballistics limitations of barrels shorter than 14.5" -- limitations in wounding potential?

In truth I probably have not thought the self defense applications through adequately. in reality, I'll likely conceal a 9mm semi-auto pistol, and would like something like a M4 for other work.  I have thought it over and don't like the idea of using a .223 rem in a urban defense mode (collateral damage risk) unless all else fails.

The 5.56 is a FAR better 'urban defense' choice than 9mm if your worried about 'collateral dammge'

5.56mm has less potential for collateral damage than your 9mm pistol or 12ga shotgun.

Any barrel shorter than 14.5" is probably better to be in something like .45ACP where a JHP bullet can be used.  There's new 5.56mm under "field testing" right now with excellent potential in shorter bbls, but it's not been standarized nor is it commonly available.
