Will the AICS 1.0 skins fit on a 1.5 chassis without any modification? The Tac Pro site says that they will, but in doing a search of this site, some have said that the 1.0 can be "modified" or "cut" to fit. Some have also posted about converting the 1.0 to use the 1.5 adj. cheekpiece. I am not concerned about doing that, but need to know if just the skins are interchangable without modification.
