I can see clearly what looks like 192 on the front lower mount and a not so distinct number on the rear mount which looks like 245918, no worries on that but it would be good to see the text and S/N on the tube to confirm, as well as you being happy the optics are going to do what they say on the box.
Normally found with matching ring numbers, the 245918 or whatever it is could be the original rifle
