From what I can tell you don't even have the hindsite. You just have the cross hair apeture from one screwed into the back of your sight mount. I see no way to adjust the cross hairs vertically. If this is the case there is no way that will work. It will be impossible to adjust to your form. If you want to use that you would have to get actual hindsite bracket so you can make the proper adjustments.
I used to have a hindsite and it worked, but not as well as a peep sight. I gave it to a buddy and he loves it, but he doesn't shoot that well to be honest so I don't think he notices the difference in accuracy. Another route you could go if you wanted to go peepless is using the No Peep. I liked it better than the Hindsite to be honest. Now I shoot well enough that if I don't want a peep, I just take it out all together. If you have consistant enough form you really don't need one for closer ranges and groups that can be effective on large game. However if you want to be really accurate and or shoot longer distances a peep sight is easier to do this with.
Basically the way you have those sights set up with that cross hair thing will not work, no way no how. But since you took it off it doesn't matter anyway.
