They came that way. At least at the time I set this thing up--ten years ago--NRS sold two different tower sizes. These taller ones work well . . . wait. Dammit. I remember doing some sort of customization of the bolts, but that may have had to do with the modification I KNOW I did to these towers, which is to put ball bearings above and below the bronze sleeves. (Yeah, I know that's crazy. But they're sure quiet . . .).
I just checked--NRS still carries both 9" and 12" pins. These are the twelves.
(To be clear: I guess we're both talking about the pins. The actual towers are NRS standard, so far as I know.)
