Extra sight housing rings if you want a different color from the standard green. Choose between standard 1-3/4" and Big Dog 2" Housing.
2016 rings will not work on previous years sights
Ordered and received in the same week.
Don't know about indoors, but outdoors the white picks up great when centering peep and both eyes open on target.
I got what i needed fast and easy. Would you use them again
Worked great ...easy to swap a color
Simple to swap out and keeps up pink accent theme on my Bowtech SR6, had to do figuring on how to set level bubble to be level with sight but got it in minutes!!!! Looks great.
