Sam,
Momentary delay - what a crapola -
I was changing out the low Opti-Locks with the X-Low's, took off the old rings and was getting ready to put on the new ones and found out one of the new rings has a ring screw hole stipped out (SHOOT).
But it gets better, as I was putting the old rings back on I spun the allen key in one of the ring screw heads - damn soft screws!
I decided to take a break before I broke anything else.
