Don't mount a stud in the "bullseye" hole because thats an amateur mistake. Thats the Marlin trademark and the hole is usually too large for the stud. Mount it just aft of there. You'll need two drill bits, one for the shank hole and the other larger bit can make a countersunk hole for the stud head. You can order a front band with a sling stud. Sometimes in the older ones you might have to do a touch of sanding to get the new band to slide on that last bit where it seats. If you do it in the right spot it won't be noticible because its under the band. I've done several of these.
