Anschutz vs UIT (AI) rails or how to attach AI to tripod?

[Anchor Zero Six]

Can anyone confirm that the legacy accessory slot on AI rifles is UIT? Is UIT same spec as Anschutz?

Suggestions on how to attach Arcra Swiss mount to AIAE without using picatinny rail adapters?

Anchor, gonna copy/paste an earlier (scout) post to illustrate how I made this work:

Recently ordered an A3 from McMillan with an Anschutz rail under the forend. RRS made an Arca-Swiss adaptor plate that should have worked great, but McM's idea of an Anschutz rail is actually thicker than Anschutz spec. in the 'shoulder' of the rail, so the RRS adaptor will not slide onto the rail.

Figured a way to use the same Arca Swiss plate used above, with an Anschutz rail t-nut from Phoenix Precision. The 10-32 hex nuts it came with were too short to grab the base thru the plate, so I swapped them for slightly longer ones:

Only thing I had to do was slightly lengthen the slot with a round file, so that all three screws could be used:

Although not as 'quick detach' as the d-ring screws & a coin, these three 10-32 screws seem to hold the plate just as securely to the rifle stock. I did consider opening up the 10-32 holes to 1/4-20 to use the screws that come with the plate, but gonna try this for a while & see how it holds up...

If you have an Anschutz rail that is 'in spec.' and not the thick shouldered rail that McM uses, then this plate from RRS is the way to go...

P.S.
this has proven to be a solid interface

Excellent thank you!

I ordered a 5 slot Anschutz pic rail made by versa pod.

I plan to run the RRS pic rail mount attached to that. Hopefully it all works and dosnt look to ghetto.

Welcome!
That Arca Swiss plate is:

So, with that Tee nut from Phoenix linked above and a couple longer screws, you could have direct-connect from your UIT(Anschutz) rail, to an Arca plate for ~$32...

Regarding UIT or Anschutz slots: Does anyone know how I can attach an ARCA rail to the UIT slot on the bottom of an Steyr SSG-08 for example?

You need a specific size.
I found it searching for Anschutz T nuts and I had to file them down slightly.

There's tons of info on the Hide answering your questions- you just need to look for it

You don't need to mickey mouse around to get camera plates to fit or use T nuts when Sawtooth Rifles and HRD Gear purpose built rails with all the attachment hardware for your AI rifle.
