Leupold Mark 4 Scope Base – 34mm, Medium, 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. A scope base bridges your receiver and your rings. It's a simple part with no tolerance for sloppy fit, because every error here multiplies by the time it reaches the reticle.
It clamps to a Picatinny rail, the MIL-STD-1913 slot pattern used on virtually every modern rifle, so mounting position is adjustable along the rail. Sized for a 34mm tube, typical of long-range scopes where maximum elevation travel matters more than weight. Medium height is the usual answer for a standard hunting scope — enough clearance for a typical 40mm to 44mm objective without raising the scope more than necessary. Aluminum construction keeps weight down without giving up the rigidity a mount needs.
