| Can anyone tell me what the threads are for a Factory drilled and tapped receiver Mossberg receiver is for mounting a rail.? I have an older receiver I want to drill and tap for a base. Thanks for any help. |

The 500, 590, 835, 930. etc all use the same hole spacing. The early guns (pre 1993? ) had 6-48 holes.
If you are drilling and tapping the receiver you can use either size, but if you buy a new base it will likely come with (and holes in the base sized for) 8-40 screws Posted Via AR15.Com Mobile |

Thanks man. |
