I inherited a Remington 513 target rifle . It is missing the plug screws for the holes in the barrel where scope blocks would be mounted. Anyone know the diameter and pitch of these screws, I would like to order some from Brownells. Otherwise, does anyone have 4 of these screws lying around they would part with? Thanks

They should be 6-48. If you have a local smith, he should have dozens laying around.

OK, great. Thanks
