AIAE MK III Scope base torque value ?

[Rprecision]

I am mounting a Murphy Precision scope base on a AIAE MK III.

What is the correct Inch Pounds of Torque ?

I tried contacting Murphy to no avail and there are no instructions with the rail.

Thanks

Per Ken Farrell instructions for his rail 20-25 in/lbs for the front screw and 25-30 in/lbs for all other screws. This is for a 20 moa rail.

I'm not sure what screws Ken is using for his rails, but our Stainless screws should only be torqued to 15 in-lbs for the #6-48 size. At 20 in-lbs, you are courting head separation. (#8-40 screws should be torqued to about 20 in-lbs though.)

Perfect, I went with 15 In-Lbs
