For now, until we get a court ruling that shoves the impending brace-ban back up ATF's craplocker--for "discreet applications" I actually prefer the old fixed SBM4 over the adjustables because it can be turned into an onboard mag carrier with no added space cost, which you can't do with the adjustables because of the track and latch hardware.

Still wish I could find someone to develop a locking hinge coupler that'd work around the QRB with "pull back to unlock/flip/pull back and latch to lock" rather than still having to fut with "manual unlock then manual join"--the game here is to shave seconds off deployment time as much as possible.
