I'm relatively new to bolt action rifles and recently acquired a (I believe 2009) 116 Weather Warrior in 300 Win Mag. The gun does not have Accustock and it is a bottom barrel release with the staggered drop out magazine. I'm aware that retrofitting an Accufit Stock will require altering the lug or replacing with an "AccuLug". I'm also aware that different variations of the Accufit stock are bottom bolt release or top/side bolt release and that the Long Action and Short Action stocks have different mounting points/distances.

My questions are:
Do Accufit stocks have different size barrel channels?
Are Accufit stocks interchangeable (taking into consideration Short/Long action, barrel release, type of magazine)?
Both of these questions are kind of the same way of asking: Will a Varmint Accustock or a Apex Hunter Accustock or any other Accustock made for a Long Action, Bottom Barrel Release, Drop Out Magazine work on my gun?

A very similar question was asked here: Is the sporter Accustock exactly the same as the heavy barrel Accustock?

Thanks for your help!
