My receiver, an SAI of recent vintage, was out of spec based on using the Sadlak kit to check it dimensionally. I really wanted the ARMS 18 due to the low profile, so I rolled the bones and went for it. It went on without a hitch. I'm not sure what the critical spec is, but it seemed to me during installation that the one thing that would really throw things off would be if the angle of the face that the stripper clip dovetails into were off, even slightly. That isn't something that the Sadlak kit measured for. FWIW... Anyway, really like my ARMS 18. Good luck!
