My frustration with AR pistol braces comes from the fact that there really isn't one that is the best of all worlds.

--I like the KAK brace but it requires a special buffer tube
--I like the SBA3 brace because it uses the milspec buffer tube, but I hate the rubber "flaps"
--I like the Tailhook 2 brace because of the hinged design, but it uses a proprietary buffer tube

So, this morning I emailed SB Tactical requesting they make a brace that uses the mil spec buffer tube but has a hinged design more like the Tailhook 2. I even stated I'd be happy with one that uses a set screw like the KAK brace if that was necessary for legality.

I'll post SB's response, if any.
