Shield CQS/SIS Picatinny Vented Mount & Spacer Triple Height

• Triple-height spacer system: The mount and spacer arrangement lets the sight sit at a height that better matches the host platform, making it easier to achieve the preferred sight picture and integration with other aiming systems.
• Vented Picatinny design: The vented body reduces unnecessary bulk while keeping a rigid mounting interface, which helps maintain a practical balance between strength and overall weight on a rifle or shotgun.
• Aluminium construction: The metal body gives the mount the durability expected for regular field use, with better resistance to knocks and repeated installation than lighter-duty alternatives.
• Shield SIS/CQS interface: Built specifically for the Shield SIS/CQS mounting standard, it provides a direct fit for compatible sights and avoids the extra complexity of improvised adapter solutions.
• Picatinny compatibility: By attaching to a common rail format, this mount expands where a Shield CQS or SIS sight can be used, from dedicated sporting setups to general-purpose long-gun platforms.

About the Shield CQS/SIS Series

The Shield CQS/SIS series is built around mounting and integration solutions for Shield CQS and SIS sights, giving users a practical way to adapt these optics to different firearms and host systems. Within Shield’s lineup, this family sits as a dedicated support range for the company’s larger reflex sight pattern, covering both straightforward rail mounting and more specialized optic-to-optic or firearm-specific interfaces.

The series includes mounts for platforms such as the Trijicon ACOG, Elcan Spectre, Browe BCO, and Cassidian/Zeiss ZO, as well as an adapter plate for Aimpoint T1 and T2 optics. Picatinny options are offered in standard, solid, and vented forms, with vented versions also available with spacer arrangements in aluminium or polymer. This makes the series useful for shooters who need to control mounting height, preserve handling, or add a compact secondary sighting solution. The overall design approach is modular and application-driven: instead of a one-size-fits-all mount, the CQS/SIS family provides purpose-built interfaces for specific roles and host platforms.

About the Shield CQS/SIS Picatinny Vented Mount & Spacer Triple Height

The Shield CQS/SIS Picatinny Vented Mount & Spacer Triple Height is a fixed red dot sight mount designed for shooters who need a Picatinny-mounted solution with more flexibility in sight height than a single-position base can offer. Its core advantage is the triple-height spacer configuration, which allows the optic to be positioned to better suit the firearm, the stock geometry, and the intended shooting style. In practice, that matters when setting up a rifle or shotgun for faster target acquisition, a more natural head position, or improved compatibility with existing sighting equipment.

The vented mount body keeps the assembly purposeful and compact while avoiding the heavier feel of a more solid block-style design. Combined with the aluminium construction, this gives the mount a good balance of rigidity and manageable weight for regular use on sporting or tactical-style platforms. At 50.00 g, it adds relatively little mass while still providing a stable base for a compatible Shield sight.

Because it is made for the Shield SIS/CQS mounting standard, this model is best suited to users who want a direct and dedicated interface rather than a universal compromise. The result is a mount that focuses on secure fit, adaptable height, and straightforward rail installation for CQS or SIS optics on Picatinny-equipped firearms.

About Shield Sights

Shield International was formed in Great Britain in 1983, and the company has long focused on firearm sighting systems for military, law enforcement, and civilian use. Shield Sights is particularly known for its work in compact reflex optics, with the original Shield mini red dot sight design dating to 1996. Over the years, Shield mini red dot sights were also sold under names including Firepoint, Tasco Optima, Trijicon RedDot, and JPoint.

The company’s product range includes mini red dot sights and rifle sights, and it also developed the Close Quarter Battlesight for the UK military before introducing the civilian-oriented Close Quarter Sportsight in 2011. A patented Mini Sight mechanism designed to allow co-witnessing with standard iron sights is another notable part of Shield’s design history. In 2013, Asset Shield Limited changed its name to Shield Firearms and Sights Limited.
