I've been using the GG&G quick detach lever actuated mount on my Eotech. it works as long as there isn't too much difference between the picatinny outside dimensions. I had hoped to be able to move it between a Ruger Frontier, a Beretta Strom, a Mini-14 Rail mount and a cantilever mount on an 11-87 slug barrel. I found it impossible to get a setting that worked reasonably for all 4. So while the QD feature works well on the same base, my hopes of switching the sight easily between rifles have been dashed...
