Nobody makes bases to fit as many guns as Weaver. Yet each base is machined to tight tolerances for a custom fit. They're 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.

"A nice base, fit perfectly, came with the two screws needed and they don't stick out into the rail itself. Has one groove as advertised. Good finish on it as well."
