I bought several pair of scope rings in different heights. Only used one set so selling these. Will sell for $45 each pair cash. Retail is $78. These are great rings for an AR or any hunting/target rifle. They are Burris Xtreme Tactical 30MM High # 420164. Also have a new set of the same rings in 1" Medium #420181.These are a strong quality ring set. See pictures. Will ship USPS for $5 extra. I am at the Weber Shooting Range twice a month. I shoot at Lee kay often and can meet there also. No trades. Call. No answer?? Leave a name/number for a call back. If you are not sure what size your rifle/scope needs, call me. I would be glad to help whether you buy these rings or not. If the AD is here the rings are available.
