Shield Sights CQS/SIS Mount for Cassidian Hensoldt / Zeiss ZO

• Dedicated Zeiss ZO fit: This mount is made specifically for the Cassidian Hensoldt / Zeiss ZO platform, giving a cleaner and more secure way to add a Shield CQS or SIS sight than a universal clamp solution.
• Shield SIS/CQS interface: The mount uses the Shield SIS/CQS mounting standard, so it provides direct compatibility with the sight family it was designed around and keeps installation straightforward.
• Aluminium construction: The aluminium body keeps weight under control while still providing the rigidity needed to hold a secondary sight in place on a working rifle setup.
• Matte black finish: The black matte surface reduces glare and matches the finish of most service and sporting optics, helping the mount blend into the host optic rather than distract from it.
• Purpose-built accessory: As part of the Shield CQS/SIS mount family, it is designed for optic-specific use, which helps preserve practical sight placement and a more natural transition to a close-range aiming solution.

About the Shield CQS/SIS Series

The Shield CQS/SIS series is a family of mounting accessories built to place Shield CQS and SIS sights on compatible firearms and optics with a dedicated, model-specific fit. Rather than relying on one generic pattern, the series includes mounts for platforms such as the H&K MP5 as well as optic-specific solutions for the Trijicon ACOG, Elcan Spectre, Browe BCO, and Cassidian/Zeiss ZO. That approach makes the range especially relevant to shooters who want to add a compact reflex sight to an existing prism or magnified optic without unnecessary bulk.

Within the series, Shield also offers adapter plates for Aimpoint T1 and T2 optics and several Picatinny mount options, including standard, solid, and vented designs. This gives the CQS/SIS line a broad role across military, law-enforcement, and civilian rifle setups. The common theme is practical integration: each mount is intended to position a Shield sight where it can be accessed quickly for close work while remaining mechanically simple and compact. For users building a layered sighting system, the series provides a consistent interface across different host optics and rifle configurations.

About the Shield Sights CQS/SIS Mount for Cassidian Hensoldt / Zeiss ZO

The Shield Sights CQS/SIS Mount for Cassidian Hensoldt / Zeiss ZO is a dedicated optic mount for shooters who want to pair a Shield CQS or SIS sight with a Zeiss ZO-series host optic. Its main advantage is not complexity but fit: because it is designed around this specific optic family, it offers a more integrated mounting solution than a universal rail adapter, helping keep the auxiliary sight positioned in a practical place for fast transitions at short range.

The mount uses the Shield SIS/CQS mounting standard, which makes it a natural match for Shield’s larger reflex sight platform. In use, that matters because the sight and mount are intended to work as one system rather than as a mix of unrelated parts. On rifles set up with a magnified combat optic or prism sight, this kind of arrangement supports a dual-role configuration: the primary optic remains in place for observation and distance work, while the secondary CQS or SIS can handle rapid target acquisition at closer distances.

Aluminium construction gives the mount the stiffness needed for repeatable alignment without adding the unnecessary mass of a heavier steel assembly. The matte black finish keeps reflections low and visually matches most tactical optics. For users who already run a Cassidian Hensoldt or Zeiss ZO optic, this mount is a straightforward way to add a compact red dot capability while keeping the overall setup tidy and purpose-built.

About Shield Sights

Shield International was formed in Great Britain in 1983, and the company has focused on firearm sighting systems for military, law-enforcement, and civilian use. Shield is particularly closely associated with compact reflex optics: its original mini red dot sight design dates to 1996, and versions of that design were sold under names including Firepoint, Tasco Optima, Trijicon RedDot, and JPoint. That long involvement in miniature sight development helps explain the company’s emphasis on compact mounting solutions and practical integration with existing weapon systems.

Shield also developed the Close Quarter Battlesight for the UK military and later introduced the Close Quarter Sportsight in 2011 for civilian users. Its Mini Sight uses a patented mechanism intended to allow co-witnessing with standard iron sights. In 2013, Asset Shield Limited changed its name to Shield Firearms and Sights Limited. Today, Shield continues to design and manufacture sights and related accessories in the United Kingdom.
