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
Even though the different colors are nice I always change my sight rings to white I feel it helps me tremendously in low light situations. I love the black gold gives you this option , try it the white really stands out the best.
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
