I've got an old Ruger 10/22, my first firearm, and I'm having an issue. I've replaced some of the internal parts (springs, extractor, etc) as well as the stock and barrel. I'm happy with the barrel (22 in stainless Green Mountain) but the stock (Ruger factory delux walnut) is a little loose on the trigger group area. The trigger group rattles around and it caused some light firing pin strikes. So I replaced the hammer spring with a new, heavier spring. This seemed to work, but the trigger group still rattles around. I want to shim it or bed it but don't know the best option. Has anyone else experienced this and what did you do?
