Just installed this on my newly acquired 650. I'm thoroughly impressed with the way it smoothed out the shell plate advancement. It just rolls into the next position and stops. I'm not sure why this doesn't come standard on a 650. It seems cheap and affective. Maybe it was just not deemed "necessary," but it sure is sweet.
Oh, I also tried just trimming down the ball detent spring a little bit. It was better, but the real improvement was the thrust bearing.
Best $6 upgrade I've spent. Just thought I would share.
Where did I get it? Here:
Go to McMaster-Carr (McMaster Carr - an awesome, just about has everything, parts supplier, that doesn't have a minimum order!), and get these parts.
