It’s going to be interesting if the trigger job has a positive effect on the accuracy. I’ve also figured it the barrel harmonics. Ruger did make a model that you could adjust the harmonics. If I recall that was .223 only and not 5.56.
It certainly ought to make it easier to shoot well. They also make a lightweight strut system to support the barrel and one version has an adjustable gas port. Not sure I want to go down that rabbit hole as the accuracy is already “service grade” and up to what I want it for. My
Howa Mini can handle the pinpoint stuff.
Ruger did make two models with a moveable weight on the muzzle; one with an oogly laminate stock and the other synthetic. You’re correct, those were .223s. The synthetic one was okay, but the laminate model was really heavy and really goofy-looking.
