I don't have a clue whether the ORC comes with the "standard" or adjustable two-stage Bushy Compass Lake knockoff trigger. If it's the adjustable trigger, then there should be a screw for adjusting the trigger pull, and I'm sure instructions are available from Bushy.
If it's the standard Bushy trigger, there is no adjustment. I opted to use the JP trigger/hammer combo, in lieu of the much-too-heavy standard Bushy trigger.
