HELP PLEASE! What size hex, torque, or what ever wrench do I need for my dagger upper RMR sights?

[Lawdog]

My upper came with one, but I lost it apparently and when I bought extremely small Allen wrenches, they didn’t work. I want to remove the optic cover plate, but I can not. Hell, I might have stripped them. What size or where can i buy a replacement wrench?

T8 torx for the plate.

RMR screws for slide

The screws provided with my Dagger slide require 2 different drivers. The rmr cover plate uses screws with a T8 torx head. While the optic mounting screws provided use a 2mm hex driver. Unsure of the optic mounting screw overall size. They appear to be 6-32 x 7/16in in length.
