EGW Universal Vortex Mount .670" Radius

• .670" radius receiver fit: The curved underside is shaped for receivers with a .670" radius, giving a lower mounting position than a rail-and-adapter stack and helping preserve natural handling.
• C-More RTS/STS footprint: Built for the C-More RTS/STS mounting standard, this plate provides a direct interface for compatible red dot sights and keeps the setup simple and compact.
• Multiple hole spreads: The mount uses several hole-spacing positions, which broadens firearm compatibility across common shotgun and rifle receivers and makes it useful for specialized hunting or field setups.
• Aluminium construction: The aluminium body keeps weight down while providing the rigidity needed for a stable optic platform on hard-use sporting firearms.
• Matte black finish: The black matte surface reduces glare and gives the mount a subdued appearance that suits practical hunting and shooting applications.

About the EGW Red Dot Sight Mounts Series

EGW Red Dot Sight Mounts are built around a straightforward idea: place a compact optic as low and cleanly as possible on the firearm while matching the mounting solution to the gun and the sight footprint. Within EGW's catalog, the series covers both rear-sight replacement mounts for pistols and dedicated plates for selected optics-ready slides, as well as receiver-style mounts for other firearm platforms. That broad approach makes the series relevant to shooters who want a direct-fit solution instead of adding unnecessary height or complexity.

A defining trait of the series is its support for widely used mini red dot patterns, including the Docter/Noblex pattern and compatible optics such as the Vortex Viper, open-emitter Vortex Venom, and Burris FastFire family on applicable models. EGW also separates footprint compatibility carefully, which matters when choosing between open-emitter and enclosed-emitter sights. Across the range, the design philosophy is practical: compact dimensions, durable aluminum construction, and application-specific geometry intended to keep the optic secure and the sight picture natural for field, competition, or general sporting use.

About the EGW Universal Vortex Mount .670" Radius

The EGW Universal Vortex Mount .670" Radius is a receiver-mount solution for shooters who need a direct way to fit a compact red dot to firearms that share this specific receiver curve. Its key feature is the .670" bottom radius, which is intended to match compatible receivers and position the optic lower than a rail plus adapter arrangement. In practice, that lower profile can improve balance, reduce bulk, and make the sight picture feel more natural on hunting or utility setups where fast target acquisition matters.

This model uses the C-More RTS/STS mounting standard, making it suitable for compatible miniature reflex sights in that footprint class. The universal layout also incorporates multiple mounting spreads, which expands fitment across a range of drilled receivers and makes the mount more versatile than a single-pattern plate. For shooters setting up a shotgun or rifle for close- to mid-range work, that flexibility is often the difference between a simple direct installation and a more complicated custom solution.

The mount is made from aluminium and finished in matte black, so it adds minimal weight while maintaining the stiffness needed for reliable optic support. At 46.00 mm in length and with 0 MOA inclination, it is designed as a straightforward, neutral mounting platform rather than a cant-compensating base. That makes it especially appropriate for red dot applications where speed, compactness, and a low mounting height are the main priorities.

About EGW

Evolution Gun Works, commonly known as EGW, was founded by George Smith in 1991. The company began as a gunsmithing shop in Doylestown, Pennsylvania and later established itself in Quakertown, Pennsylvania, United States. EGW designs and manufactures firearm parts and accessories, with a product range that includes scope mounts and scope rings, red dot mounts, thread protectors, 1911 parts, and AR and rifle components.

That background is directly relevant to products like this mount. EGW's reputation is built on practical mounting solutions for shooters who need correct fit, solid machining, and application-specific designs rather than generic hardware. Its long involvement with optic mounts and handgun parts is reflected in products that focus on footprint compatibility, low-profile installation, and durable construction for regular field and range use.
