I just saw this today and it is really interesting. Its basically a special barrel nut and and a hand guard with a quick release lever. You can get a kit to build a grendel version for $695.00 after looking at if for a minute I thought is that really better than just pulling the two pins to separate the upper from the lower. I guess it packs down a little shorter. What do you think?
