You are offerding on a vintage Sako rear peep sight. Peep set for 100 or 200 yards. It looks new. I don\'t think it\'s ever been on a rifle. Fits on factory dovetail. Measures approx 9/16 to outside edge of dovetail. I believe SAKO measured these using metric measurement. That would put this at just over 14mm. Pics tell story best. See pics. and ask questions. Please do not offer if you can\'t own these in your home state. I ALWAYS COMBINE SHIPMENT ORDERS IF YOU SEE SOMETHING ELSE YOU LIKE IN MY OTHER sales. Payment and Shipping Instructions: Immediate shipment upon payment by bank check or MO. Other payments must clear prior to shipment. Buyer to pay $7 for insured shipping in US.
