Does anyone know the the size / thread of the screws that go into Ruger scope rings?
Are they all he same?
Where can replacement screws be purchased? Just need a few.
Thanks

Well I found them on Ruger.com.
Size 6/40. They sell an upgraded version with Hex heads for $6.95 for 8 screws.
I should have known to look there first.

If you call Ruger they're likely to send you a few for free …..
