Weaver Ext Series Scope Bases

Weaver Ext Series Scope Bases

Carefully selected optics that fit the modified RMSc footprint, no guesswork required.

Find scope bases compatible with Weaver rails and from the Ext Series all in one place. We stock these direct from the brand so you get current production every time.

The base sets the alignment for every component above it. Match the screw pattern to your receiver exactly before ordering. Most manufacturers list bases by specific action model. Two-piece designs give flexibility in scope position; one-piece Picatinny bases maximize ring placement options and overall rigidity.

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.
