Overview

The Sportsmatch TO3 (also known as the TO3C) is a high-quality, British-made two-piece scope mounting system designed for 1-inch (25.4mm) tube optics. Engineered for rifles with standard 11mm to 3/8" (9.5mm to 11.5mm) dovetail receiver grooves, these medium-height rings provide a solid and reliable connection between your rifle and optic. Unlike single-screw alternatives, the TO3 features a double-screw design on both the base clamps and the ring caps. This configuration significantly increases clamping force, preventing scope slippage caused by recoil while ensuring your scope tube is secured without pinching or stress. Precision machined from high-tensile aircraft-grade aluminium, this lightweight mount set offers exceptional durability without adding unnecessary bulk to your rifle setup.

Key Features

• Double-Screw Security: Features dual screws on both the ring caps and base clamps for enhanced grip and resistance to recoil shift.
• British Craftsmanship: Manufactured in Great Britain using precision-machined, high-tensile aircraft-grade aluminium for exact alignment.
• Dovetail Compatibility: Designed to fit standard 11mm and 3/8" (9.5mm to 11.5mm) receiver rails, which are standard on many rimfires and air rifles.
• Medium Height Profile: Safely accommodates scopes with an objective lens diameter of up to 45mm on most rifle models.
• No Regulatory Restrictions: As a non-powered, purely mechanical firearm accessory, this product requires no SAA safety approvals or RCM markings, and can be legally purchased and shipped directly to residential addresses across all Australian states without a firearms license or Permit to Acquire (PTA).

Who It Is For

The Sportsmatch TO3 scope mounts are ideal for Australian rimfire shooters and air rifle enthusiasts who demand high-precision optic security. Whether you are setting up a .22 LR or .17 HMR bolt-action rifle for small-game hunting, or mounting a scope to a medium-power air rifle for backyard pest control and target shooting, these mounts provide the stability needed for consistent accuracy. The medium 19mm saddle height is perfect for shooters using popular mid-sized optics who want to maintain a comfortable cheek weld while keeping the line of sight as close to the barrel axis as possible.
