Whelen B,
Yes that is a KS. The earlier ones had Brown Precision stocks. Mine is identical to that one. Same stock, and same Camo paint scheme... I believe at that time they were also available with the "Battleship Grey" paint, as well.
Dang handy little rifles... Light and easy to handle... They will, however, get your attetion with the heavier loads..
(One whould hope, however, that whatever you aim it at is suitably impressed...)
The only Remington Custom Shop catalog I have shows only the Grey ones...
