Advertising these for a friend, 25mm blue'd medium rings in mint condition, never been used outside or on the range. He bought them second hand from a shop were they was just used to mount a scope to a gun for a client to see how a scope looked on the gun. They have been mounted to his gun, unscoped for past couple of month's while he decided what scope to buy, anyway he has ended up with a 30mm one so no use for these. wants 40ono. if your interested i will pass his number on to you, or yours to him.
