WARNE M902/924M Winchester Model 70 w/.860 RHS Matte Steel Base

The WARNE M902/924M Matte Base Set is a heavy-duty, two-piece scope mounting base designed for Winchester Model 70 rifles with .860″ Rear Hole Spacing (RHS). Machined from steel and finished in matte black, this Maxima® base provides a strong and low-profile foundation for Weaver-style scope rings and optics. Its design supports recoil resistance and offers solid alignment for shooting and hunting applications.

Key Features

Tailored Winchester Fit:
• Designed specifically for Winchester Model 70 actions with .860″ RHS, ensuring precise alignment to the receiver’s drilled and tapped holes.

Two-Piece Steel Construction:
• Solid machined steel deliver rugged strength more resistant to deformation under recoil compared with lighter materials.

Weaver-Style Cross Slots:
• Base incorporates a traditional Weaver slot pattern compatible with a wide range of scope rings and mounting hardware — ideal for common optic setups.

Low-Profile Matte Finish:
• Matte black surface reduces distracting glare and mixes well with many rifle and optic finishes for a tactical and hunting-ready look.

Full-Width Recoil Slots:
• Each piece features a full-width recoil slot, giving crew lugs on compatible rings the maximum bearing surface for firm engagement.

Hardware Included:
• Mounting screws are provided for attaching the base securely to the rifle receiver.

Technical Specifications

Rings and additional mounting hardware are not included.

Performance & Practical Use

This Warne Maxima base set adds a robust mounting platform to Winchester Model 70 rifles that lack a built-in rail. Its steel construction and Weaver-style slots create a dependable framework that helps keep your scope stable under recoil and enhances your rifle’s versatility with a wide selection of rings.

The low-profile design allows you to mount optics close to the bore axis while often retaining the ability to use iron sights when optics are removed — particularly useful with quick-detach rings such as Warne’s Maxima QD series. The full-width recoil slots help ring recoil lugs seat firmly, improving repeatability and alignment during repeated shooting sessions.

Best Suited For

✔ Winchester Model 70 owners needing a two-piece matte base
✔ Shooters who want Weaver-style ring compatibility
✔ Hunters and target shooters mounting traditional optics
✔ Field use where strength, durability, and low profile matter

User Tips

Confirm Hole Spacing:
Ensure your Model 70 has the .860″ Rear Hole Spacing (RHS) before purchasing — the base won’t fit variants with different hole patterns.

Proper Torque:
Tighten mounting screws to manufacturer-recommended torque specs (often ~25 in-lbs) to prevent loosening under recoil and to protect receiver threads.

Clean Contact Surfaces:
Before installation, wipe the receiver’s mating surface to remove oil and debris for maximum seating contact.

Choose Compatible Rings:
Pair with quality Weaver-style rings that fit your scope tube diameter and desired eye-relief height.
