Model K98 manufactured by Gustloff Werke in 1944. The bcd is the manufacturers code and the 4 under it is the marking used in 1944.
Your sporterized gun has nonmatching parts as shown by the variety of numbers on the various parts that do not match the guns serial number.
It's no sniper rifle judging by the three holes for the rear scope and how the forward one is misaligned with the rest. The holes are for a Weaver / Redfield mount and another set are for a special Redfield mount that was for military Mausers that didn't have the receiver flattened and retained the clip slot.
