Thanks @VSP968 very helpfulOnly if it is an AT AICS chassis that looks like this will the hinge work on the AT rifle because the hinge is bolted and bonded to the chassis.

Earlier AICS like this are pinned with 8mm pins and bonded together and will not “bolt on” the AT rifle chassis.

The front skins absolutely will not fit, however the butt skins are a direct bolt on to the hinged AT butt skeleton because the dimensions of the L shaped skeleton have never changed on any folding AI rifle with a thumbhole.

Thae chassis i'm looking at is the newer type.
I incorrectly assumed you could buy a hinge and add it to the AT.
Might have to break out a hammer and blowtorch to convert it and run the AT chassis on the bergara 22 trainer...
