{/quote} This is incorrect!
If you have a registered SBR (EVO) and configure back to a standard pistol, you can cross state lines without any issues as it is not an SBR in the original configuration. Just because it is registered as an SBR it doesn't mean it's an SBR if it is not configured as such.

This makes more sense to me. If you configure it back to its original configuration, how will anybody know it had once been SBR'd unless they check, and even then, it's not an SBR if its in its original configuration. The tax stamp should only apply when the EVO is in the SBR configuration.
