The Weaver Tactical Extended Multi-Slot Picatinny Base for Winchester Model 70 Long Action gives you a solid, adaptable platform for mounting optics on one of America's most respected rifle actions. Built from aircraft-grade 6061-T6 aluminum and hard anodized to Type-III specifications, this base combines proven durability with thoughtful engineering. The extended design adds roughly an inch of forward length, opening up mounting flexibility whether you're running a traditional scope setup, a modern tactical configuration, or experimenting with different optic positions to find what works best for your shooting style.
This isn't a base that tries to do everything—it does what Winchester Model 70 shooters actually need. The multi-slot design works seamlessly with both Picatinny and Weaver-style rings, so you're not locked into a single ecosystem if you already have rings on hand or want to swap components later. USA manufacturing means attention to detail in the machining and finish; you can see it in how the slots align and how the matte coating sits.
Installation matters, and Weaver publishes torque specs for this base: 15 in-lbs for 6-48 screws and 18 in-lbs for 8-40 screws. That precision carries through to how the base performs—tight, repeatable, and reliable season after season.
| Material | Aircraft-grade 6061-T6 aluminum |
| Finish | Type-III hard coat anodized, matte |
| Compatibility | Winchester Model 70 Long Action; Picatinny and Weaver-style rings |
| Design | Extended multi-slot (adds approximately 1 inch forward length) |
| Recommended Torque (6-48 Screws) | 15 in-lbs |
| Recommended Torque (8-40 Screws) | 18 in-lbs |
| Origin | USA-made |
Yes. The multi-slot design is engineered to accept both Picatinny and Weaver-style rings, giving you flexibility if you already own compatible rings or want to use different ring types.
The extended design adds approximately one inch of forward length, which increases your mounting options. Some shooters use it to move optics forward for better eye relief, longer scope eye boxes, or to clear high-powered magnification scopes on shorter actions.
This base is specifically engineered for Winchester Model 70 Long Action. Do not use on a Short Action without confirming compatibility with Weaver or your gunsmith.
Weaver specifies 15 in-lbs for 6-48 screws and 18 in-lbs for 8-40 screws. Use a torque wrench to achieve the proper tightness without over-torquing, which can damage the aluminum.
