Rab-ad flaw?? - Stern Defense RAB-AD Series Rapid Attach Buttstock Adapter

Glad I already had a couple on order before reading the review from AJ about a "flaw". After the concern that reading his review caused me, I decided to install then torture test before deciding to depend on it on one of my carry guns......after rapid fire tests, including mag dumps with a Franklin Armory binary trigger, which is as rapid as I can go, I never could get one to accidentally detach, I even went so far as to try to find a shooting position that I could accidentally push the release, never could make it happen. After playing with it and figuring out that it seems to work with the .22lr conversion without having the buffer tube reattached, I picked up a few more for my carry guns. So far I've had no fitment or rattling problems and will be installing a few more soon.
