Frequently Asked Questions

What torque value should be used for installing a Badger Ordnance scope base?

For the Badger Ordnance 20 MOA scope base, the recommended torque specification is 15 inch-pounds (in-lbs). Always use a calibrated torque wrench to ensure accuracy and prevent damage to the base or receiver.

What are the essential tools for installing a rifle scope base?

Essential tools include a high-quality screwdriver set with appropriate bits (like Brownells Magna-Tip with hollow-ground bits), a torque wrench (like the Brownells Magna-Tip Torque Handle), and a degreaser/solvent such as LPS A-151 or acetone.

Why is degreasing important before applying threadlocker?

Degreasing screw holes and fasteners removes oils and contaminants, ensuring the threadlocker (like Red Loctite) can properly bond and create a permanent, moisture-sealed fit. This prevents screws from loosening due to recoil.

What is the 'recoil shoulder' on a scope base and why is it important?

The 'recoil shoulder' is a feature on some scope bases designed to interface with the rifle's receiver. It must be pushed forward against the ejection port area to properly absorb and manage recoil forces, preventing the base from shifting.
