C-More TSK Tactical Spacer Kit

• Tactical height increase: The spacer kit raises a compatible C-More Railway setup by .180 in., helping tactical rifle users achieve a more practical sight height for AR-platform use.
• Lower 1/3 co-witness setup: When used on AR15, M16, and M4 flattop rifles and carbines, it supports a lower 1/3 iron-sight co-witness, keeping the red dot clear while leaving backup sights immediately available.
• Railway-standard compatibility: Built around the C-More Railway mounting standard, this spacer fits naturally into existing Railway-based setups and simplifies configuration changes without moving to a different sight system.
• Aluminium construction: The aluminium body keeps the kit light at 80.00 g while providing the rigidity needed for a stable mounting interface on hard-use red dot sight installations.
• Purpose-built accessory: As a dedicated C-More mounting accessory, the TSK is designed for shooters who need to adapt sight height to the rifle rather than compromise with a one-position mount.

About the C-More Accessories Series

The C-More Accessories series brings together the supporting hardware that lets C-More sights be adapted to different firearms, mounting heights, and shooting roles. Within the company’s Parts & Accessories range, the series includes practical items such as Railway base clamps, a Railway base, and the Tactical spacer kit, all aimed at tailoring how a sight sits on the gun. This makes the series especially relevant for shooters who already know the sight they want but need the mounting geometry to match a specific platform.

The range also reflects C-More’s long-standing focus on modular red dot systems. Alongside mounting parts, the accessories lineup includes interchangeable diode modules for full-size sights and support items such as batteries and lens-care tools. In practice, that gives the series a clear role: it is not a generic add-on catalog, but a set of purpose-built components for maintaining, configuring, and refining C-More red dot sight setups. For competition, tactical rifle use, or general range work, these accessories help users tune fit, height, and handling without abandoning the underlying sight platform.

About the C-More TSK Tactical Spacer Kit

The C-More TSK Tactical Spacer Kit is a compact mounting accessory made for shooters who need a taller red dot sight position within the C-More Railway mounting standard. Its main job is straightforward but important: it adds height between compatible Railway-pattern components so the sight sits in a more useful position on rifles that benefit from a raised optical line. That is particularly relevant on AR-pattern carbines, where sight height affects both head position and how the dot aligns with backup irons.

In practical use, the TSK is most valuable when building a lower 1/3 co-witness arrangement. Instead of placing the iron sights directly in the center of the viewing window, this setup keeps them lower in the lens, leaving a less obstructed sight picture for faster dot acquisition while still preserving immediate access to the irons. For tactical optics and defensive-style rifle configurations, that balance can make the sight picture feel less crowded during rapid target transitions.

The kit’s aluminium construction supports that role well. It keeps weight to 80.00 g, so it adds useful mounting height without turning a compact red dot setup into a bulky one. Finished in black, it also matches the visual profile of typical C-More sight and mount combinations. For shooters using compatible Railway-standard components, the TSK offers a simple way to optimize mounting height without changing the sight itself.
