Shield Picatinny Vented Mount & Spacer SIS/CQS

• Vented Picatinny design: the vented structure keeps the mount light while preserving a stable platform for a Shield SIS or CQS sight on a Picatinny rail.
• Spacer-equipped mounting system: the included spacer concept allows the sight height to be configured for the host setup, which helps when matching the optic to irons, cheek weld, or surrounding equipment.
• Shield SIS/CQS interface: built specifically for the Shield SIS/CQS mounting standard, it gives a direct and purpose-made fit instead of relying on a generic adapter solution.
• Polymer construction: the polymer body keeps weight down to just 15.00 g, making it a practical choice where added bulk on the firearm should be kept to a minimum.
• Picatinny compatibility: by adapting a Shield SIS or CQS sight to a Picatinny rail, this mount broadens installation options across rifles, carbines, and other platforms that use the common rail standard.

About the Shield CQS/SIS Series

The Shield CQS/SIS series is built around mounting solutions for attaching Shield CQS or SIS sights to a wide range of compatible firearms and optics. Within the Shield lineup, this family serves as the interface between the company’s compact rifle sight systems and the host platform, making it relevant for users who need a secure, application-specific way to position a red dot on different weapons or optical housings.

The series includes Picatinny mount options in standard, solid, and vented forms, along with optic-specific mounts for platforms such as the Trijicon ACOG, Elcan Spectre, Browe BCO, and Cassidian/Zeiss ZO. Shield also lists dedicated solutions for the H&K MP5 and an adapter plate for Aimpoint T1 and T2 optics. That breadth shows the design philosophy of the series: keep the sight interface consistent while tailoring the mount to the job. In practice, that gives users a cleaner fit, more predictable sight placement, and a mounting system chosen for the geometry of the firearm or optic rather than a one-size-fits-all bracket.

About the Shield Picatinny Vented Mount & Spacer SIS/CQS

The Shield Picatinny Vented Mount & Spacer SIS/CQS is a fixed mount designed to place a Shield SIS or CQS sight onto a Picatinny rail with minimal added mass. Its main advantage is straightforward adaptability: it converts the dedicated Shield SIS/CQS interface into a widely used rail format, so the sight can be installed on rifles, carbines, and other rail-equipped platforms without changing the optic itself.

The vented polymer construction keeps the assembly light at 15.00 g, which matters on compact firearms where excess weight high on the receiver can affect balance and handling. The vented pattern also gives the mount a more open structure than a solid block design, helping reduce unnecessary material while still providing the fixed support expected from a non-adjustable mount.

What makes this version especially practical is the spacer-based setup. Rather than locking the user into a single sight height, the mount is intended to work with spacers so the optic can be positioned to better suit the firearm configuration. That can be useful when aligning the red dot with existing sighting equipment or when setting the optic at a height that gives a more natural head position. For users running a Shield CQS/SIS mounting standard optic and needing a simple Picatinny solution, this mount focuses on low weight, direct compatibility, and a cleaner installation.

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. Its product range includes mini red dot sights and rifle sights, with a background that is closely tied to compact reflex optic development.

One of the company’s defining milestones is that its original mini red dot sight design dates to 1996. Shield mini red dot sights have also appeared under names such as Firepoint, Tasco Optima, Trijicon RedDot, and JPoint, reflecting the influence of its early designs across the category. Shield later developed the Close Quarter Battlesight for the UK military and introduced the Close Quarter Sportsight in 2011 for civilian users. The company is also known for a patented Mini Sight mechanism designed to allow co-witnessing with standard iron sights.
