Question about AI AT AICS r700 chassis

[Jcaplinger199]

I am building a 308 with a bighorn origin and a proof savage small shank prefit. I want a folding stock. I’ve always liked the look of the Ai AT. I assume the AI AT AICS r700 chassis should accept the origin action as it’s a rem700 clone. But will it have enough clearance for a savage small shank barrel nut? Using a NSS nut. Thanks
