Sorry for being so ignorant on the subject, but will ANY Zeus part fit any ZEUS marker? Such as the Warsensor parts fitting Armotech. Is there even a difference between the two other than the company?

EDIT: Just read an old archive saying external accessories are interchangeable, internals are not. Correct?
