Clip guides have no distinction over commercial or military, almost every single commercial Mauser Oberndorf has them. Also the Model 98 action since its inception was built also as a commercial rifle, that was in 1897. The actions from this early timeframe are small ring, lack a bolt shroud detent, firing pin cams, have narrow gas ports etc, but are still a true Mauser 98 with third bolt lug. Many of these actions as described made their way to Rigby and Sauer and feature very low Mauser serials on the lower receiver flat. The Suhl/Z-M region had a long history of obtaining surplus and rejected military actions and made significant use of them for as new built commercial rifles, you see this all the way through the end of WW2. Generally, only your higher end makers, eg. Sauer, Merkel etc purchased new commercial Mauser actions, and even then, not in every case were these used in new builds. A significant amount of surplused actions made their way to Suhl from both the state arsenals and the myriad of commercial producers of the Gew98 in the interwar era. Very often you will still see the evidence of this, a first right receiver position fraktur inspection, indicating the receiver was never previously completed into a rifle. In no way shape or form, can a rifle be considered “sporterized” in this scenario and a lot of people have trouble with that distinction.
