I’ve had trouble with the same saddle that I purchased with my Mach2 two years ago One of the locks sticks into the dovetail area preventing me from tilting in a dovetail and forcing me to slide it in. It’s a minor nuisance so I haven’t said anything and if I hadn’t seen this, I wouldn’t have. If there’s a fix I’d love to get it. It has only affected one of three locks.
