From what I understand, the accustock recoil lug is "v" shaped and will need to be swapped out if you transition to a different stock. You can buy an aftermarket recoil lug for a new stock. They are thicker and are more true. You can get them from SSS or NSS (both site sponsors).

I'd stick with what you got. Many claim 0.5 MOA stock. You can also decrease action friction with the DIY trick using a .357 mag. case and a ball bearing. I assume a .38SP case will work as well. If it's not accuracte enough, I would bed and buy a match grade barrel. Accutrigger is already pretty good and if it doesn't already have a target trigger, all you need to do is swap out the spring to lighten the pull, although, it's already pretty light.
