Rugers may have the best factory barrel made in the US right now contrary to popular belief. I watched them making them on a TV show a few months back and there are operating rooms that aren't as clean. Evidently Mr Ruger was tired of the poor quality of Wilson barrels so he brought in a famous custom barrel maker . I believe his name is Bill ATkinson and had him run the barrel department. I have always had topnotch accuracy with M77's.
