C-More STS Scope Tube Mount - 1 inch

• 1 inch scope tube fit: This mount clamps to a 25.4 mm (1 inch) riflescope tube, making it possible to add a compact C-More red dot without changing the main optic or moving to a rail-mounted setup.
• C-More RTS/STS interface: The mount uses the C-More RTS/STS mounting standard, so it provides a direct platform for compatible miniature red dot sights and keeps installation straightforward.
• Aluminium construction: The aluminium body keeps weight down while still providing the rigidity needed for a secure optic mount on a hunting or sporting rifle.
• Offset red dot solution: By placing a micro sight on the scope tube, this mount supports a fast secondary aiming option for close targets while the primary magnified optic remains in place for longer shots.
• Part of the C-More MRD mount system: As part of the C-More MRD Mounts family, it fits into a broader mounting ecosystem designed around C-More miniature reflex sights and different firearm or optic interfaces.

About the C-More MRD Mounts Series

C-More MRD Mounts are built around the company’s compact red dot sight footprint and are intended to give STS2-style micro sights a practical mounting solution across a wide range of firearms and optic setups. In C-More’s lineup, this family sits as the supporting hardware for miniature reflex sights rather than as a universal one-size-fits-all mount system. The series includes dovetail mounts, Weaver/Picatinny options, 3/8-inch rail mounts, scope-tube mounts, and firearm-specific kits, which makes it suitable for pistols, carbines, and rifles using different host platforms.

A defining characteristic of the series is its focus on application-specific fit. Some mounts are made for particular pistols such as Glock, Beretta 92, and Sig P226 models, while others adapt the same sight pattern to optic-ready cuts or to riflescope tubes. That approach matters in practice because it lets the shooter keep the compact handling of a micro red dot while choosing a mount that matches the firearm or optic already in use. Across the range, the design philosophy is simple: provide a stable interface for compatible C-More STS, STS2, RTS2, or RTS3-pattern sights where the individual mount allows it.

About the C-More STS Scope Tube Mount - 1 inch

The C-More STS Scope Tube Mount - 1 inch is a specialized red dot mount for shooters who want to add a compact reflex sight to a riflescope with a 25.4 mm (1 inch) tube. Instead of replacing the primary optic or adding a separate top rail, this mount uses the scope tube itself as the attachment point. That makes it a practical choice for rifles already set up with a traditional hunting or sporting scope, especially when a fast secondary aiming reference is useful at short distance.

The mount uses the C-More RTS/STS mounting standard, giving it compatibility with the appropriate C-More miniature sight pattern. In practical use, that means a shooter can pair a magnified optic for deliberate shots with a compact red dot for rapid target acquisition, transitions, or close-range work. This kind of setup is especially useful when the main scope is set at higher magnification and a wider, faster sight picture is needed for nearby targets.

Aluminium construction helps keep the mount light enough that it does not add unnecessary bulk to the rifle, while still offering the stiffness needed to hold a micro sight securely. Because it is purpose-built for the 1 inch scope tube format, it suits riflescope setups that still use the classic 25.4 mm tube diameter rather than newer 30 mm or larger bodies. For shooters invested in the C-More sight ecosystem, it is a clean way to expand a magnified optic setup with a compact red dot capability.

About C-more

C-MORE Systems has offered sights since 1993 and is based in Warrenton, Virginia, United States. The company is known for its work in red dot sights and rifle scopes, with product lines that include the RTS2, STS2, RTS3, CRC, Railway, Slide Ride, and Serendipity. That product range shows a clear focus on reflex sighting systems for sporting, competition, and firearm-specific applications.

Alongside its optics, C-More also makes mounting hardware for its sights, which is particularly relevant here because the brand’s miniature red dots are supported by dedicated adapters and mounts for different firearms and optic interfaces. The company also offers the C3 1-6x24 rifle scope, showing that its expertise extends beyond reflex sights into magnified optics as well. In practical terms, C-More has built a reputation around giving shooters both the sight and the mounting solution needed to fit it to the intended platform.
