The only question I have is, What does the hinge do? Installation looks similar to attaching one of those peep aligners, loosen and move until your peep is aligned with the pull of your nocking loop. What is the hinge for??
The hinge is to aid in applying the Peep to the string. By slightly closing and securing one of the screw’s allows you to check that the Peep is in proper placement. If all is to your liking then secure the QSE peep in location with both screws. To keep in mind that the screws need only to be snugged not torqued to maintain the QSE in location.
Hope this helps and good shooting.
Sorry for the delay in response as I have been busy with product development and upgrading.
