C-More STS/STS2/RTS2 Rail Mount - Weaver / Picatinny

• Weaver / Picatinny interface: This mount lets compatible C-More micro red dot sights attach to one of the most common rail standards, making it a practical choice for rifles and chassis systems that already use a cross-slot rail.
• Fits C-More STS, STS2 and RTS2 pattern sights: The mount is built around the C-More micro sight footprint, so it provides a straightforward way to move these optics onto a rail-equipped platform without changing to a different sight system.
• Aluminium construction: The aluminium body keeps weight down while still providing the rigidity needed for a stable optic mounting platform, which helps preserve zero through regular handling and field use.
• Part of the C-More MRD mount family: As part of C-More’s dedicated micro red dot mount range, it is designed to match the company’s miniature sight ecosystem rather than relying on generic adapters.
• Broad firearm compatibility: In addition to standard Picatinny rails, this mount suits a wide range of compatible rifles and chassis platforms, giving shooters a simple route to fit a C-More micro sight across different setups.

About the C-More MRD Mounts Series

C-More MRD Mounts are built around the company’s miniature red dot sight footprint and give users a dedicated way to place these optics on different firearms and mounting surfaces. In C-More’s lineup, this family serves as the bridge between the compact STS2-type sight body and the many rifles, pistols and rail systems shooters actually use in the field or on the range.

The series includes dovetail mounts, Weaver/Picatinny rail mounts, 3/8-inch rail mounts, scope-tube mounts and firearm-specific kits, so the concept is not a one-size-fits-all adapter but a modular mounting system. That matters in practice because miniature red dot sights are often used across very different platforms, from rimfire pistols to centerfire rifles. C-More also lists dedicated options for models such as Ruger Mk II, III, IV and 22/45 pistols, along with other optic-ready interfaces and slide cuts. Across the series, the distinguishing feature is compatibility with the company’s micro sight pattern, with specific mounts supporting STS, STS2 or RTS2 depending on the design. The result is a mount family aimed at shooters who want to keep the same sighting system while adapting it to a particular firearm or rail standard.

About the C-More STS/STS2/RTS2 Rail Mount - Weaver / Picatinny

The C-More STS/STS2/RTS2 Rail Mount - Weaver / Picatinny is a fixed mount designed for shooters who want to place a compatible C-More micro red dot on a conventional cross-slot rail. Its role is straightforward but important: it converts the compact sight body into a practical rail-mounted optic setup for rifles, chassis rifles and other platforms that use a Weaver or Picatinny rail. That makes it especially useful when the firearm does not have a direct-mount optic cut but already provides a standard rail interface.

Because it is made for the C-More RTS/STS mounting standard, the mount keeps the installation within the same sight ecosystem rather than forcing the use of improvised plates or universal adapters. For the shooter, that means a cleaner fit and a more purpose-built connection between optic and firearm. The aluminium construction helps keep the assembly light, which is valuable on compact carbines, hunting rifles and rimfire setups where unnecessary top weight can affect balance and handling.

This mount also suits users who move a sight between multiple compatible firearms. A rail-based solution is often the simplest way to share one optic across several hosts, especially when those hosts already use Picatinny rails. In practical terms, this C-More mount is about compatibility, low added weight and a direct path to mounting an STS, STS2 or RTS2-pattern sight on a widely used rail standard.

About C-more

C-MORE Systems has offered sights since 1993 and is based in Warrenton, Virginia, United States. The company focuses on sighting equipment, particularly red dot sights and rifle scopes, and it is especially well known for developing multiple electronic sight lines for different shooting applications. Its red dot range includes the RTS2, STS2, RTS3, CRC, Railway, Slide Ride and Serendipity families, covering everything from compact slide-mounted optics to larger competition-oriented designs.

A notable part of the brand’s approach is that it also produces dedicated mounting hardware for its sights, allowing the optic and mount to remain within the same design system. That is directly relevant here, because products such as this rail mount are intended to give C-More miniature sights a more secure and application-specific fit across different firearms and rail types. Alongside its red dot products, the company also offers the C3 1-6x24 rifle scope.
