Thread: What detachable sling swivels fit a CZ 457 synthetic.

Tried to fit some Uncle Mikes today on behalf of a mate to the rifle in the subject line. The stud is molded as part of the stock and the sling swivel pin won't fit through the hole in the stud. It is the owners first rifle he has ever owned and when I suggested drilling out the stud holes, the look I got was not one of encouragement. I would be reluctant too in the event that the drill bit were to catch and rip through the molded stud.

Is there a specific sling swivel to fit this rifle? Is it a matter of just pushing the sling swivel pin harder (maybe I was too gentle)?. I tried two separate sets of swivel and neither fitted.
Looking forward to input from anyone who has had success solving this problem.
