This guide, presented by Chad, details the professional installation of a scope base on a Remington 700 AAC-SD using a Badger Ordnance 20 MOA steel billet rail. It emphasizes proper degreasing, the use of Red Loctite, and precise torque application with a torque wrench to ensure a secure and reliable scope mount. The instruction highlights the importance of the 'recoil shoulder' on the base and a final bolt clearance check.

Quick Summary

Proper installation of a rifle scope base involves degreasing screw holes and fasteners, applying Red Loctite, and using a torque wrench to achieve the manufacturer's specified torque, typically 15 in-lbs for scope bases. Ensure the base's 'recoil shoulder' is seated correctly and check bolt clearance post-installation.

Frequently Asked Questions

What is the recommended torque specification for installing a Badger Ordnance scope rail?

The Badger Ordnance scope rail, as shown in the video, has a recommended torque specification of 15 in-lbs. Always consult the manufacturer's documentation for your specific scope base and firearm.

Why is degreasing important before installing a scope base?

Degreasing the screw holes and fasteners is crucial to ensure proper adhesion of threadlocker. This prevents the scope base from shifting under recoil and also helps to create a moisture seal, protecting against rust.

What is the purpose of the 'recoil shoulder' on a scope base?

The 'recoil shoulder' on a scope base is designed to butt against the front of the rifle's receiver. This feature absorbs recoil forces, preventing the scope base from moving rearward and maintaining zero.

What type of screwdriver bits are recommended for scope base installation?

It is recommended to use hollow-ground bits, such as those found in the Brownells Magna-Tip screwdriver set. These bits fit precisely into screw heads, minimizing the risk of marring or stripping them during installation.
