The Sako Optilock Blue 1? Medium Rings are precision-machined, blued steel scope mounts designed to work with rifles that feature Sako’s integral Optilock receiver rails. They securely hold a 1? diameter scope tube at a medium mount height, providing an ideal balance between low-profile alignment and adequate clearance for larger objective lenses. Finished in a durable blue steel, these rings come packed in pairs with the necessary hardware for straightforward installation, and their precise fit helps maintain scope alignment and return-to-zero performance shot after shot. This makes them a reliable choice for shooters who want quality, stability, and ease of use when mounting optics on a Sako or compatible rifle.
