Leupold Standard Cooper Arms 38/21/57 Scope Base – Black
Leupold has been machining scope mounting hardware in Oregon since long before most of the current market existed, and their ring and base systems are the reference other makers get compared against. The base is the foundation of a scope mounting system — it bolts to the receiver and gives the rings something square and solid to clamp to. Get this part wrong and nothing above it can be right.
It mounts directly to the receiver, so fitment is specific to the action it was machined for — check the fit before ordering. Steel construction adds weight but resists deformation under clamping force better than aluminum, which is why it stays popular on hard-kicking rifles.
