Each Weaver base is machined to the tightest tolerances for a custom fit. They are designed to fight the effects of recoil with a square-cut notch that precisely mates to the sturdy cross bolt in every Weaver detachable ring. Custom-hardened fastening screws come with every Weaver base. The Weaver #70 Scope Base is a 1-piece base. Mounting hardware is included.
