Leupold 8 40 Screws Scope Bases

Our Leupold scope bases inventory is all here. All products are current production, sourced directly from the manufacturer.

The base is where every alignment decision downstream gets set. Leupold machines their bases to the receiver screw pattern and face angle so they install flat without shimming. Match the base to your specific action model, torque to spec, and add a thread-locking compound if the rifle will see high round counts.

Confirm whether your rifle uses Mil-Spec 1913 Picatinny, Weaver grooves, or drilled-and-tapped receiver holes before ordering. Each product page lists the specific action or rail compatibility.

Each product ships for free.
