Try a few, throw all sizes at it then see what sticks.

It's not a critical fitting o-ring so some simple measurements should get you there.
Measure the diameter of the adjuster (o-ring ID)
Measure the width of the adjuster slot (o-ring Width)
Measure the diameter of the counter bore in the back of the trigger (o-ring OD)
My guess would be:
The ID probably wont have a stretch so it's likely to be the same diameter as the o-ring ID
The slot width will probably be a tad wider than the o-ring width to allow for a compression fit
And the ring OD will be 'just' bigger than the bore diameter in the trigger to allow for a compression fit
Check your Buna-N O-Ring chart to find the correct size, it should pretty easy to figure out
