Will this Leupold Backcountry rail fit both my Savage 110 Long Action and Savage Axis rifles with round receivers?

Yes, model 187346 is precision-engineered specifically for Savage 110 Long Action (LA) and Savage Axis rifles featuring a round receiver. It is a 1-piece matte base offering zero MOA cant and is crafted from durable 7075-T6 aircraft aluminum. Please note it is designed strictly for round receivers and will not fit short-action or flat-back receiver variants.

What screw sizes are included in the packaging for mounting this base to the receiver?

This adaptable mounting platform includes two complete sets of mounting screws in the box: both standard 6-48 thread sizes and heavier-duty 8-40 screws. The recommended maximum base-to-receiver screw torque is 22 in-lbs. This versatility allows you to accommodate modified receivers or heavier-recoiling setups securely.

Are there any Australian electrical or RCM compliance requirements for this Leupold scope base?

No, because this is a purely mechanical firearm accessory machined from solid aluminum and contains no electronic components, active power circuits, or batteries, electrical standards such as RCM, SAA certification, and 240V mains power compatibility are entirely not applicable.

What kind of scope rings can I attach to this cross-slot rail system?

The cross-slot design of this Leupold Backcountry base is universally compatible with both standard Picatinny and Weaver-style scope rings. For a seamless setup using Leupold gear, you can pair it with compatible rings like the Leupold Backcountry Ring Mount series to maintain an ultra-rigid, lightweight optical platform for outback hunting.

Savage 110 Scope Base - Leupold LE187346

The Leupold BackCountry Cross-Slot Savage 110/Axis Round Receiver LA (Adaptable) 1-Piece Matte Base (Model: 187346) is a precision-engineered mounting platform designed specifically for Savage long-action rifles featuring a round receiver. Machined from a single block of high-grade 7075-T6 aircraft aluminum, this base provides an ultra-rigid, lightweight connection between your rifle's receiver and your optical system. By eliminating the potential points of failure found in multi-piece mounting systems, the one-piece construction ensures consistent ring alignment, reliable zero retention, and robust recoil resistance under harsh field conditions. It is engineered with a matte black, non-reflective finish to minimize glare during outdoor operations.

Key Features:

High-Grade 7075-T6 Aluminum: Crafted from premium aircraft-grade aluminum, offering the structural strength of steel at a fraction of the weight, measuring approximately 62 to 68 grams (2.2 to 2.4 ounces).
One-Piece Rigidity: Enhances alignment and structural integrity, absorbing heavy recoil and ensuring consistent optical zero retention.
Adaptable Screw Configuration: Packaged with two complete sets of mounting screws, including both heavy-duty 8-40 screws (ideal for heavy-recoiling or modified actions) and standard 6-48 thread sizes.
Cross-Slot Design: Provides highly flexible ring placement options, making it universally compatible with both standard Picatinny and Weaver-style scope rings to achieve optimal eye relief.
Low-Glare Finish: Features a matte black anodized surface that resists scratches and eliminates reflections in bright Australian outdoor environments.
