Will the Sportsmatch HTO75 mounts fit my CZ 550 rifle action?

Yes, the HTO75 model is specifically designed for 17mm receiver dovetails such as those found on the CZ 550, CZ 557, ZKK600, and Brno 601/602 series rifles. It also features three removable steel recoil arrestor pins to prevent scope slippage under heavy centrefire recoil in harsh Australian bush conditions.

What objective lens size can I use with these high-profile 30mm scope mounts?

The Sportsmatch HTO75 provides a height to the ring saddle of 20mm and a 30mm ring diameter, allowing you to comfortably accommodate rifle scopes with up to a 56mm objective lens diameter on most standard rifle configurations. The two-piece design also leaves the breech area clear, ensuring easy cartridge loading and ejection during your hunts.

Do these scope mounts require any electrical compliance or SAA/RCM certifications for use in Australia?

No, as the Sportsmatch HTO75 is a purely mechanical firearm accessory made from high-grade aircraft-specification hardened Duralumin, electrical compliance standards such as 240V compatibility, SAA approvals, and RCM certification are completely non-applicable.

17mm Scope Mounts - Sportsmatch HTO75

Sportsmatch HTO75 17mm 2 Piece 30mm High Scope Mounts

The Sportsmatch HTO75 is a premium-grade, two-piece double-screw scope mounting system manufactured in the United Kingdom. Specifically engineered to fit 17mm receiver dovetails (which typically measure approximately 19mm at the widest top point of the receiver), this high-profile mount accommodates rifle scopes with a 30mm body tube and objective lenses up to 56mm in diameter. Precision-machined to ensure optimal alignment, the HTO75 utilizes a two-piece configuration that provides shooters with maximum mounting flexibility. This design keeps the rifle's breech area completely clear, allowing for fast, unobstructed manual cartridge loading and reliable case ejection during high-pressure shooting scenarios.

Key Features of the Sportsmatch HTO75:

High-Tensile Fasteners: Features a robust double-screw clamping system on each ring, providing exceptional holding power and preventing movement under heavy recoil.
Recoil Arrestor Pins: Equipped with three removable steel recoil arrestor pins that mechanically lock the mount into the receiver, eliminating scope drift.
Premium Materials: Constructed from high-grade, aircraft-specification hardened Duralumin for lightweight durability without compromising structural integrity.
Optimised Breech Clearance: The two-piece split design ensures easy access to the action for loading individual cartridges or clearing jams.
Precision UK Manufacturing: Developed and produced in Great Britain using advanced machining processes to guarantee tight tolerances and reliable return-to-zero performance.

Who the Sportsmatch HTO75 is For:

The Sportsmatch HTO75 is specifically designed for Australian sport shooters, recreational hunters, and professional pest controllers who operate classic or modern European centrefire rifles. Since robust actions like the CZ550 and Brno ZKK series are widely utilised across Australia for managing feral pig, wild goat, and deer populations, these mounts provide the necessary stability required for harsh regional conditions. This mounting solution is ideal for shooters upgrading to larger 30mm tube optics with up to 56mm objective lenses, ensuring consistent accuracy, absolute zero retention, and rugged performance in demanding Australian outdoor environments.
