When I return from a forthcoming deployment I'm going to build an AR pistol around the new Sig brace. I've been on the fence for a while, but this review on an upcoming tube made for the brace has me excited about an essentially legal non-NFA SBR. http://sigforum.com/eve/forums/a/tpc/f/630601935/m/5570079063
I'm thinking 10.5" LWRC IC upper on the Odin lower.
Also possible I'll try the Sig 556 10" pistol. I've got some time to chew it over.
Anyone with experience using the Sig brace? I've seen plenty of YouTube videos and read reviews, but never gotten to hold one myself.
