Ax acis pre2014 questions?? 338 edge build

[Nomad909]

I'm building a 338 edge. I want to use an ax aics chassis that's pre2014, I like those buttstocks better. I found one for sale and it's what I'm looking for (I think). The current owner only uses normal length 300wm magazines 3.64ish I believe.. he does not know if it's CIP length/capable chassis and does not have a magazine to test this. What do i do??

I read the comment from the AI rep. Earlier in (another) thread. The way I understand it is all ax aics are CIP?? Some later comments contradict that..

Please clarify this for me, thanks in advance

I found this post in an earlier thread but this reps comment was contradicted by other members later on.. just looking for clarity here.
