Here's a set of factory Ruger 1" rings, high height and they're the same height, so NOT for a M77, but any Ruger that takes the same height rings. Rings are blued and have new, correct, T10 screws in them, no tip included. $30 delivered to your USA address, check or usps m/o for payment, no PayPal and no trades please. Thanks for looking, Dean.
