Re: AICS stockside interchangeability?
As I understand it, all of the AI skins are the same basic piece of polymer, but they vary depending on where they're cut-whether short or long action, cut-out for the bolt handle/buttspike/etc. Generally speaking you need skins that are specific to the weapon's type and configuration - short-action AE skins won't work on a long-action AICS, etc.
