APS stand for a 170 question.

[Mkeller088]

Can anyone tell me what size the aluminum excursions are an IM APS 170? I’m waiting on delivery, and I can’t find any information anywhere. I’d like to use some 8020 hardware but have no idea what size or type of slots the Stans have. If anyone can enlighten me please do.
