How would I put a swivel stud for the front of a mossberg 500. I already got one in my stock.

Uncle Mike's:

Page down to Mossberg set Number 18102 and 18105

If this isn't waht you want, Mike's sell a wide variety of mount systems.

If you ever purchase a new barrel for your Mossberg 500, the barrel lug is pre-drilled and tapped for a sling swivel stud. You can get one from Mossberg direct for a couple of dollars. The previous post with the Michaels of Oregon rig is probably a more durable sling mount because the sling swivel stud is attached to a large bolt. I have had no issues with the Mossberg stud though.

I went to wal-mart and got the one for the 500 how do I tap it do i just drill a hole or do i need some kind of drill bit?

Edit: I got the one for most pumps and autos
