There used to be instructions over on Go Go Varmint Go in the tech section on how to set these up. Since it's the same trigger as the 541 without the adjustment screws, it's no big deal to add them and have a nice fully adjustable trigger. You can do this to the 788 as well. If you're not familiar with doing trigger work, see if you can find someone who is - you don't want to mess it up since they aren't available anymore.
