I'm considering building a SBR. If I get the stamp and register the lower, it is my understanding I could use any number of short barreled uppers on the one receiver. Is that correct?

yes you can use other uppers in different barrel lengths and calibers.

check out the sbr and class 3 forums under the "armory" tab

Keep in mind that you are supposed to be able to recreate the original stamped configuration or notify the BATFE of the permanent change.

When your stamp comes back, you must initially build it in the configuration that was mentioned on your Form 1. As soon as you do that, you are free to change it up however you want (caliber, length, brand, etc). There is no requirement that you have to be able to bring it back to it's original configuration or notify the ATF when you change it.

Really? I've been doing this a long time and i never knew this! I thought that once approved the lower receiver could only use the barrel length and caliber of the approved form one. I'm not doubting you; i just didn't know this.

Nope - you can use what ever upper you want as long as you have the ability to restore it to the original configuration (or amended configuration if you sent them a letter)

Nope, swap uppers at will. However, NFA would like to be notified of any "permanent" change to the weapon's registered configuration. From ATF's website:

"Q: May the short barrel on an SBR or SBS be replaced with a long barrel for hunting or other purposes, with the intent of replacing the short barrel?

Yes, and you will not be required to again register the firearm before replacing the short barrel. ATF recommends written notification to the NFA Branch when a firearm’s configuration is permanently changed or removed from the purview of the NFA."
