Not sure what the max LOP of the TCS is while still keeping full engagement of the butt pad columns in the KMW hardware, but if you needed it longer it would not be difficult to make longer columns for the butt pad assembly.
My hunch is about 14.5-14.75 max LOP with the stock columns, but I'll try and remember to check tonight.
