Description
Getting glass on your Savage B-Series doesn't need to be complicated, and this Weaver Classic Aluminum Base Pair keeps it simple. You get a matched front and rear base cut specifically for the B-Series rimfire family, so there's no guessing on hole spacing or hunting down two mismatched pieces. The bases are machined from lightweight aluminum that stands up to recoil while keeping weight off the top of your little rimfire, which matters more than folks think on a gun you carry all day in the squirrel woods or out plinking.
Why the Savage B-Series Fit Matters
Savage's B-Series covers the B17 in .17 HMR, the B22 in .22 LR, and the B22 Magnum in .22 WMR. These bases are made as a matched pair for those receivers, so you're mounting to a platform that's drilled and tapped from the factory for Weaver-style bases. No adapters, no filing, no fuss. The compact two-piece layout also leaves your ejection port and action clear, which makes loading and clearing a whole lot easier than a long one-piece rail would.
Cross-Lock Design and Ring Compatibility
The real workhorse here is Weaver's cross-lock channel. It grabs onto any Weaver top mount cross-lock ring for a tight, repeatable fit that holds zero shot after shot. If you've already got a set of Weaver rings in your kit, they'll drop right in. Running two separate bases instead of a solid rail also gives you a little wiggle room on ring placement, so you can slide things fore and aft to dial in eye relief for your particular scope.
Built in the USA
These bases are made in the USA and carry Weaver's reputation for tight machining tolerances. Weaver's recommended torque on the 6-48 mounting screws is 15 inch-pounds, and a drop of blue thread locker is never a bad idea on a rimfire that sees a lot of range time. Set them right the first time and they'll ride along quietly doing their job for the life of the rifle.

Frequently Asked Questions
Which rifles does the Weaver Classic Base Pair fit?
This matched pair is cut for the Savage B-Series rimfire rifles, which includes the B17 in .17 HMR, the B22 in .22 LR, and the B22 Magnum in .22 WMR. Savage drills and taps these receivers for Weaver-style bases at the factory, so the pair drops right on. It's always smart to confirm your receiver's hole spacing before ordering.
Do these bases come with rings?
No, the set includes just the front and rear bases plus mounting screws. You'll add your own Weaver top mount cross-lock rings sized to your scope tube diameter. Any standard Weaver cross-lock ring will seat in the base channel.
Are these a Picatinny rail or a two-piece base setup?
These are a classic two-piece Weaver base pair, not a single Picatinny rail. The compact design keeps the action and ejection port clear and lets you shift ring placement to fine-tune eye relief. If you're running a long, large-objective scope, a one-piece rail might suit you better, but for most rimfire builds this pair is plenty.
How tight should I torque the mounting screws?
Weaver recommends 15 inch-pounds on the 6-48 mounting screws. A drop of blue thread locker helps keep everything put on a rimfire that sees regular range time. Use an inch-pound torque wrench so you don't strip the threads on the receiver.
