There are two concepts involved here, and they are different:
literal KISS
KISS as a concept
literal KISS = the notion that the rifle must be as basic and simple as possible. This usually winds up in the ultimate expression of a gun with A1 sights, a fixed stock, either no sling or a carry strap and no forward assist. This means the gun istself is as stripped down and as simple as possible.
KISS as a concept = a rifle configured to make life simple for the end-user. I won't rehash what the previous posters listed, but all of those items (CCO, light, "tactical" sling) make life simpler for the end-user in a variety of situations.
So, apples and oranges... you need to determine what "KISS" best suits your needs.
