Figured out adjustment mentioned in bad reviews. - Vortex Precision QR Extended 30mm Cantilever Mount

There really should be some instructions included with this mount. There are two quick release levers, with no apparent way to adjust their tension to be able to affix it to the rail. One of the levers was too tight so I tried loosening the screw with a screwdriver, not realizing the head of the screw is an octagonal shape sunken in an octagonal hole. So I marred both the screws right away which is frustrating. I realized then that if I push the lever in towards the opposite side, it exposes the adjustment screw head which is then easily turned with just your fingers. A couple minor adjustments tighter/looser and the mount is easily affixed securely to the rail, and easily removable. It’s so simple yet not apparent at all when you first are trying to mount it.
