DINGDINGDING! We have a winner! There's still the one other thing that no one will probably notice, but the biggie is the side bolt release. I sent the action in for a rebarrel/cerakote and went ahead and had my gunsmith mill .078" off the side of the receiver. I already had the sear, and that's all that's needed to do away with the trigger guard bolt release.
