Weaver 654 Top Mount Base Features The Weaver Mounts 654 Top Mount Base is machined to tight tolerances for a custom fit on the Savage 110 action ensuring the base sits flush and square against the receiver. Built from aluminum the base offers strong holding power for rings while keeping overall weight on the rifle to a minimum. The rock solid Weaver cross-lock design is one of the most proven mounting standards in the industry and it accepts a wide range of Weaver and Picatinny-pattern rings rather than locking the shooter into a single ring brand. That flexibility makes it easy to pair this base with whatever ring height or style best suits the optic being mounted. Mounting hardware is included and the base attaches to the Savage 110 receiver using 8-40 inch length screws for a secure repeatable fit every time the base is installed or reinstalled. The matte black finish matches typical rifle and optic finishes keeping the installed look clean and factory-correct. Because the base is purpose-fit to the Savage 110 s 8-40 screw pattern there is no guesswork or drilling involved in getting a scope base properly seated. For Savage 110 owners looking for a dependable well-fitted base to start their optic mounting setup the Weaver 654 Top Mount Base is a solid proven choice.
