A lot of people have bemoaned the fact there are no aftermarket triggers for the Remington gas guns. The problem is, nobody wants to risk giving someone a trigger they can adjust until the gun starts to double (or triple or quadruple).
You might call and talk to some of the gunsmiths who work on gas guns for service rifle matches? I'm not saying they will do the work, but may be able to steer you to someone who does. Ask Compass Lake or even Springfield Armory if they know of someone who works on this action's trigger? They may hesitate to make an outright recommendation because of the liability chain, but might at least drop a name.
Good luck with it.
