The Slide Ride was originally designed to mount directly to the slide of Glock handguns, which proved the durability and reliability of the C-MORE design by withstanding the rigorous pounding motion of recoil. But the Slide Ride has also become the sight of choice for "custom" applications because of its ability to attach to any flat surface. This enables the sight to be mounted directly to the firearm or a custom made mount, allowing the sight to be applied to applications that may not provide standard mounting options.. Runs on a 3 volt lithium battery for up to 1500 hours of continuous use.
