Normal ASA: Holes go all the way through, screws dig into threaded hole in gripframe
BackBottle ASA: Holes in ASA are threaded, they don't go all the way through, the screws mount from the top of the rail and go down into the ASA
I think that's the difference. (Never held one so I have no idea if the spacing is different as Crash indicates)
