RAI 10/22 screw size

[Paatz]

Does anyone know offhand what the size is for the scope mount screws on these RIAs?

I think they are smaller than Ruger's'.

And does anyone have some or know where to get them?

Yes they are different size than the ruger.
I’m on holidays on my iPad but search ria-22 and search the threads somewhere in there we discussed the thread pitch of them.

Great thanks.

Well after searching I have not found an answer.
Perhaps they are metric thread?

 

[wayupnorth]

They are defiantly a course thread

I know At home I have pics comparing ruger and ria screws side by side.
Which doesn’t help as I’m not at home.

I could run one down to the local machine shop next week when I get home, maybe he can ID the tread?

The only reference I could find was Hitzy retapped his receiver to 6-48.

That's probably the best option, but I've never tapped a thread before.

That's very generous of you thanks, but please don't go out of your way. You should have a thread guage anyways...!

I went to Nut and Bolt in Lloydminster. I took one of the old ones and they measured it and got me the longer ones I needed. The Bolt Supply House in Winnepeg look like they offer the same products. Maybe try calling them to see if they can help.

If I had the screws I wouldn't be asking...
