Will the Leupold Open Range Rail fit my standard .22 LR rifle or air rifle?

Yes, the Leupold Open Range Rimfire 1-Piece Base is specifically designed to fit most .22 caliber rimfire rifles and high-powered air rifles equipped with standard factory 11mm or 3/8-inch receiver dovetails.

Do I need a gunsmith to install the LE184809 base on my rifle?

No gunsmithing is required. This mount features a convenient no-tap installation that clamps directly onto your existing receiver dovetails, allowing you to easily convert your rifle into a versatile cross-slot rail system at home.

What kind of scope rings can I use with this Leupold 1-piece base?

Once installed, this base converts your native dovetail into a robust cross-slot rail that accommodates standard Weaver-style scope rings of any height or size. If you are looking for a complementary optic setup in our range, it pairs exceptionally well with scopes like the Leupold VX-Freedom Scout 1.5-4x28 Riflescope.

Are there any Australian regulatory or electrical certifications needed for this scope mount?

Because the Leupold Open Range Rail is a purely mechanical mounting accessory constructed from lightweight aircraft-grade aluminum, it does not contain electrical components and is therefore exempt from SAA or RCM certification and 240V power requirements.

Rimfire Scope Base - Leupold LE184809

The Leupold Open Range Rimfire 1-Piece Cross-Slot Base (Model LE184809) provides a highly stable and durable mounting platform for small-caliber firearms and air rifles. Designed to slide directly onto standard 11mm or 3/8-inch receiver dovetails, this single-piece base converts a native rimfire mounting surface into a robust cross-slot, Weaver-style rail. Manufactured from lightweight, high-strength aircraft-grade aluminum and finished in a non-reflective matte black, it offers a secure bridge between your rifle and your chosen optic. For Australian shooters looking to upgrade their rimfire rifles without permanently altering their receiver, this base delivers a rugged, slip-free solution that withstands repeat firing and field use.

Key Features

No-Tap Installation: Installs directly onto existing 11mm or 3/8-inch receiver dovetails, completely eliminating the need for drilling, tapping, or professional gunsmithing.
Cross-Slot Adaptability: Easily converts narrow, traditional rimfire rails into a standard Weaver-style cross-slot platform, enabling the use of wider, high-strength scope rings of any size or height.
Aircraft-Grade Aluminum: Constructed from premium, lightweight aluminum to minimize added weight while maintaining structural rigidity and resisting impacts.
Matte Black Finish: Features a durable, non-glare matte black finish that matches most modern scopes and receivers.
Enhanced Recoil Resistance: Delivers a solid clamping surface that prevents scope movement and zero shift during extended firing sessions.
Australian Legal Status: Classified as a non-regulated firearm accessory, this mechanical mounting rail is fully legal to buy, own, and ship to customers across all Australian states and territories.
