These came off a scope that I bought. The guy I bought the scope from had just bought the rings and they are like new. Unfortunately He didnt no if they were highs or extra highs, and I have no idea as well. If anyone has any way to tell feel free to let me no. Anyway I had to go buy medium rings and dont need these. Ill let them go for $90.00 TYD. These will be on other forums so the first Ill take it followed by a pm get them. I will time timestamp if need be. Thanks in Advance.
