LAW folders aren't cheap, so whatever cash you save from going DI will get eaten up when you add in the LAW folder, receiver extension, buffer, action spring, and brace or stock.
Seems like a good deal. Still wish it was a <10" barrel. I'm finishing up a 12.5" 5.56 gun which will serve as a GP biathlon/competition gun. Still want a folding Rattler type thing for not Rattler money, so this may be it.
