LR308 lower too wide for ambidextrous selector

[JWard]

I have a Daytona Tactical (was 80%) lower that is too wide to accommodate an ambidextrous selector switch. The selector will clamp down on the sides of the LR308 lower when the screw is tightened but it fits an AR15 lower fine. Of the dozens of ambidextrous selectors I've seen, all say they are one-size-fits-all AR15 and LR308. The external width of the AR15 is 0.885" and the LR308 is 0.911". I haven't been able to find a specification for the width in question so I don't know if I should be looking for a selector that is wider or if my lower is out-of-spec (if common) considering that all selectors should supposedly fit. What do you think?

If it is the Billet Aluminum one I use the Radian Talon Ambi's on identical ones no problem. BUT, the Radians are a generous fit on the forged AR15 lowers.

Battle Arms Development BADASS Ambi Safety Selector is made wider, just for things like this.  That was it's purpose, but they designed it in 2010,with no idea how far out these new .308AR 80% people would go.  Maybe it will work, maybe it won't.  It's the only one that was made for that reason, though.  It's worth a shot.
