I was wondering if anyone knew the thread pitch for the new mini tactical rifles integral mounts these two holes Attached File If like to buy aftermarket screws for a mount I'm trying to make and wondered if anyone knew. Rugers closed for the holidays, but I'll bother them on Monday if need be. thanks |

I do not know for sure, but 6-48 and 8-40 are the most common optic base screw sizes....but Ruger often uses 6-40 for sights and other parts. Do you have any of those 3 on hand to try? (The front sight screw on a Ruger Mark 2/3 22 auto pistol is 6-40) |

I'm not sure why, the only thing I can think of is it fits in the cut for the rear ring nicely I really have no idea why |

It looks like that 5-40 hole is just the right size/width to fit in the Ruger ring slot, and it you get too heavy handed and strip the threads in that hole(s) you can easily retap to 6-40 or 6-48. |
