Will the Durasight DS400B rings fit my 30 mm scope tube or a Picatinny rail?

No, these rings are strictly engineered for 1-inch (25.4 mm) main tubes and standard Weaver-style rails. If you are mounting a larger 30 mm or 34 mm scope body, you will need an alternative model as these will not fit.

What is the maximum scope objective lens size I can use with these medium rings?

The Durasight DS400B medium rings safely accommodate scopes with up to a 44 mm objective lens. If you are running an optic with a larger 50 mm or 56 mm objective lens, you will need to step up to high-profile rings like the Durasight DS302B to ensure adequate barrel clearance.

How do the quick-detach cam levers perform in rugged Australian bush conditions and do they maintain zero?

The integrated QD cam levers allow for toolless scope removal in the field, making them ideal for transitioning to backup iron sights in dense scrub or packing down your rifle for transport. Constructed from proprietary Z-2 zinc alloy and secured with Grade 8 Torx fasteners, they are engineered to withstand heavy centrefire and magnum recoil while providing reliable return-to-zero capability.

Are there any Australian electrical or safety compliance certifications required for this product?

No, as the Durasight DS400B is a purely mechanical firearm accessory, electrical compliance certifications such as 240V, RCM, SAA, or AS/NZS standards do not apply. They are uninhibited hardware accessories readily used across Australian hunting platforms.

Scope Rings DS400B - Durasight DS400B

The Durasight Z-2 Alloy Weaver Vertical Split QD Scope Rings – Medium Black (Model: DS400B) are quick-detach optical mounting rings designed to secure 1-inch (25.4 mm) rifle scopes to standard Weaver-style bases. Constructed from proprietary molded Z-2 zinc alloy, these rings provide approximately 50% more tensile strength than standard aluminum mounts while maintaining a lighter profile than steel. Featuring an integrated quick-detach cam lever system and a two-piece vertical split design, they allow toolless optic removal and reattachment in the field while maintaining return-to-zero reliability across heavy centrefire and muzzleloader recoil.

Key Features

Z-2 Zinc Alloy Build: Delivers high tensile strength to withstand repetitive magnum centrefire and muzzleloader recoil forces without adding excess weight.
Toolless Quick-Detach Levers: Integrated cam levers allow rapid field removal and optic swapping while maintaining return-to-zero alignment.
Vertical Split Design: Utilises heavy-duty Grade 8 Torx fasteners to apply balanced, uniform clamping pressure around delicate 25.4 mm optical tubes.
Corrosion-Resistant Finish: Coated in an industrial matte black powder coat for durability and weather resistance in field environments.

Who is the Durasight Z-2 Alloy Weaver Vertical Split Qd Scope Rings - Medium Black for?

Centrefire and rimfire hunters requiring toolless removal — Provides quick-detach cam levers on these scope rings to remove and remount 1-inch (25.4 mm) tube optics on Weaver rails without losing zero.
Dense-bush hunters using backup iron sights — Enables rapid detachment of scopes with up to a 44 mm objective lens via toolless quick-detach scope rings to instantly transition to open or ghost-ring sights.
Muzzleloader and magnum rifle shooters — Uses high-tensile Z-2 alloy construction and Grade 8 Torx hardware in these quick-detach scope rings to withstand heavy recoil on 25.4 mm main tubes.

Less suitable for: Rifle setups utilizing larger 30 mm or 34 mm main tubes, or optics with objective lenses exceeding 44 mm in diameter; these require dedicated 30 mm/34 mm rings or high-profile mounting rings to maintain adequate barrel clearance.
