Of the ones I tested...the one that worked the best for my purpose was the Badger TRAMP and I've got 3 of them now. One on a 6-9, one on a 7-13 and one on a 12-27 (or something like that)
The ADM was a very close second, but it's not a ture QD by definition, because it takes skilled hands or two hands to install and remove. That's a good thing. The GGG was to easy to snag and have fall off.
The Larue LT130 was similar to the ADM, but without the locking mechanism.
