The Warne 7666M-20MOA fits Savage AccuTrigger short-action rifles with round receivers, including models 10, 11, 12, 14 and 16, as well as the newer Savage 110 short-action configuration. It is designed for receivers using standard 6-48 mounting screws. Savage AccuTrigger receivers drilled and tapped for larger 8-40 screws require the Warne 7664-20MOA instead. This rail is not designed for the Savage Model 25.
A 20 MOA rail angles the scope mounting surface to provide additional elevation adjustment when dialing for longer shooting distances. This added cant helps preserve usable upward scope adjustment for long-range shooting, particularly when the riflescope has limited internal elevation travel. The Warne 7666M-20MOA is the 20 MOA version of the Savage short-action Mountain Tech rail. For a level mounting platform without built-in elevation, the corresponding 0 MOA model is the Warne 7666M.
Warne Mountain Tech rails are precision CNC machined from 7075/T6 aluminum for a strong, lightweight mounting platform. The Mil-Spec hardcoat anodized finish provides abrasion and corrosion resistance, while black zinc-coated mounting hardware adds protection against environmental exposure. Self-centering tapered T-15 Torx screws provide a secure receiver attachment.
The one-piece rail accepts compatible Picatinny and Weaver-style scope rings and is NATO-STANAG compatible. Its continuous cross-slot mounting surface allows flexibility when positioning rings to achieve proper scope eye relief.
The 7666M-20MOA includes self-centering tapered T-15 Torx mounting screws for Savage receivers using standard 6-48 threads. Warne recommends a maximum mounting screw torque of 25 in-lb and the use of removable thread-locking compound on base and rail installations. Clean oil and grease from the receiver screw holes, mounting screws and contact surfaces before installation. Follow the rifle manufacturer's torque specifications if they specify a lower limit.
Savage rifles use different receiver configurations and mounting screw sizes, so selecting the correct rail requires more than identifying the model name. Our Picatinny Rail Fitment Guide explains how to identify your rifle and choose a compatible scope base.
The 7666M is the 0 MOA version, while the 7666M-20MOA has 20 MOA of built-in elevation. Both fit the same Savage AccuTrigger short-action round-receiver configuration. The 20 MOA version provides additional scope elevation adjustment for longer-range shooting.
Yes. It fits the newer Savage 110 short-action configuration when the receiver uses the standard 6-48 mounting screws. Confirm that your rifle has the round-receiver AccuTrigger mounting pattern.
No. The 7666M-20MOA is designed for standard 6-48 mounting screws. For a compatible Savage AccuTrigger short-action receiver drilled and tapped for 8-40 screws, select the Warne 7664-20MOA.
No. Warne specifically excludes the Savage Model 25 from the 7666M-20MOA fitment. This rail is intended for the AccuTrigger round-receiver short-action configuration.
Warne recommends a maximum of 25 in-lb for the rail-to-receiver mounting screws. Warne also recommends removable thread-locking compound for base and rail installations. Do not confuse this mounting screw torque with the torque specifications for scope ring cap screws.
The rail accepts compatible Picatinny and Weaver-style scope rings. Choose rings that match your riflescope's main tube diameter and provide the appropriate height for objective clearance and shooting position.
Twenty minutes of angle (MOA) is the amount of built-in elevation cant in the rail. The angled mounting surface gives the scope additional upward adjustment for dialing at longer distances. It does not change the rifle's zero by itself.
