Those are the semi auto only with a 16" barrel. If you want, you could SBR one and have the shorter ~6-8" barrel (not sure what size). The only way that people have full auto versions of these is if they are a Class III dealer and get a CLEO sign off on a "Demo Letter" to demo them for a department.
The more I think about it, the more I am really liking these guns. They are really smooth to shoot, considerably more so than most other .45acp carbines. Not to mention they use Glock 21 mags and are very space efficient when you take a look at the design. Darn, another one to add to "the list"! LOL
