OK here is what I got from my friend.
He shot a 16" barrel version and was very impressed (as I said he ordered the SBR). He said it was easy to handle, very lightweight but, as advertised, almost no recoil. He was shooting indoors at 25 yds and getting a 2-3" pattern without much effort. He would recommend getting the optional foregrip for the max accuracy.
He wasn't thrilled I brought it up .. he is having a hard time waiting on his tax stamp
