300 Win Mag Scope Bases

Browse our scope bases inventory. Every product is sourced directly from established manufacturers and selected for build quality and reliable fit.

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.
