I have a brand new set of Night Force rings that are 30mm and are .5" height. They have not been used before. I also have a set of Badger Ordinance 30mm rings that are the low rings. These rings have been lapped and we used for a short time. I will take $100 TYd for the Night force rings and $80 for the Badger rings. Both sets were payment to me for a hunting jacket I had and I don't have a need for them as of now so I am just selling or would trade for other hunting/ gun stuff. (Especially an aftermarket bolt handle for my SA savage build as partial trade)
