I would also like to know this if anyone has any info.

I will be first to say I don’t know, when I torque my trigger group down I use 25-35 inchlbs

M6 x 20mm trigger assembly screw has a recommended torque of 55-65 in-lbs to the action.
Aftermarket trigger manufacturers are also recommending this torque spec in their replacement kits.
Heres a link to one aftermarket kit so you can verify…

Wow 65 in-lbs is tight…  I wonder why the high specs
I have twisted the ends off otherwise beefy seeming screws at 50 in-lbs

Thats in/lbs not lbs….thats not an uncommon torque spec for this bolt or assembly.
No different than an action screw directly to a chassis…metal to metal contact.

30 to 35 inch lbs. sounds like it would be about right .
