Hi guys and gals, was just thinking how does the ACR on the Kohler Mags really work. What is the mechanical process and what controls it. Just something that I was wondering about,never to old to learn something new. As always, Thank you for your responses and sharing your knowledge. Bob UP DATE I did some more searching and found a post of Steves (Stevasaurus) that explained the ACR through pictures and words very well ! Thank you Steve.
